An exotic form of magnesium oxide is referred to as Caustic Calcined Magnesite (CCM), a highly reactive and highly reversible form of magnesium oxide. It is manufactured by burning naturally occurring magnesium carbonate (magnesite) between 800 and 1500 degrees Celsius. In powder form, this substance appears white or yellow in color and is available in a variety of strengths. As there are different types of caustic calcined magnesia available in different purities and particle sizes, it can be used in a wide range of applications due to its versatility.
Furthermore, due to its high reactivity, purity level, and surface area, caustic calcined magnesia has also been in high demand in industries such as agriculture, industrial, chemicals, construction, environmental, steel, refractories, and cosmetics.
Magnesite balls are made using caustic calcined magnesia as a raw material. To create the balls under high pressure, the caustic calcined magnesia is combined with water and a binder. The magnesite balls are also utilized to create a converter slag splashing composition regulator and an efficient protective slag layer on the furnace liner.
Additionally, caustic calcined magnesia is used in environmental applications for flue gas treatment, waste neutralization, and soil decontamination. It is anticipated that the market will grow during the forecast period as a result of an increase in interest in environmental applications in the near future.
The caustic calcined magnesia market is divided into segments based on application, including agricultural, industrial, chemical, construction, environmental, steel, cosmetic, and others. The strong demand for caustic calcined magnesia from a variety of applications, however, results in scarcity. These further limits its use in a variety of applications, although Yingkou Sinosun Chemical Co., Ltd. (China) is a reliable source of caustic calcined magnesia that satisfies customer needs.
We’re about to dig a little deeper into the details of the application of Magnesium Oxide, also known as Caustic Calcined Magnesite:
Feed additives
Magnesium levels necessary for a balanced animal diet are frequently lacking in plant forage and animal feeds. Generally, magnesium supplementation is required for the purpose of regulating magnesium levels in the diet of animals. Grass tetany is a disorder brought on by magnesium insufficiency in sheep, cattle and other animals. In the spring and fall, when the quantities of magnesium in the animal’s natural feed are insufficient to sustain healthy levels, this disease is more prevalent. To ensure that the animals receive the proper amounts of magnesium to stop grass tetany, feed supplements and mineral premixes are frequently utilized.
Agriculture Fertilizer
Magnesium oxide, or MgO, that has undergone caustic calcination is ideal for making a variety of fertilizers that contain magnesium. Due to its role as the major component of the chlorophyll molecule in plant tissue, magnesium is a crucial mineral for plant development. The lack of chlorophyll in a plant with a magnesium deficiency causes poor and stunted plant development. Caustic calcined MgO can be added to fertilizers during the neutralization or granulation phases of the process to serve as a source of Mg nutrition.
Hydrometallurgy
A binding reagent for the efficient operation of the hydrometallurgy process is magnesium oxide. Maximum purity to precipitate the hydroxide of precious metals like cobalt, nickel, and uranium from acid-leached solutions, Caustic Calcined Magnesite (CCM), is utilized. Magnesium oxide increases the precipitate grade and has high metal recovery capabilities. The benefits of caustic calcined magnesia also include adequate and progressive pH regulation. The metal hydroxide particles multiply and disperse more quickly. The solid has a higher concentration of metallic sludge produced. Compared to a sludge made with lime or caustic soda, the dewatering procedure is simpler.
Abrasive
As part of a process for producing abrasive bodies (grinding wheels, emery stones, millstones) which contain particulate abrasive materials, such as magnesium oxide and magnesium chloride, as binders, a polycarboxylic acid is employed as the plastic for forming the bodies. By reacting the polycarboxylic acids with magnesium ions, the moulded abrasive bodies are bound or hardened without the need for heating, and they can be used as abrasives.
Chemicals (Magnesium Salts) / Construction (Flooring, Ceiling Boards)
The performance of magnesium oxide board is unaffected by water absorption, like that of any sheathing board. Consequently, it can be used inside and outside, as well as in wet areas like showers. Both structural and semi-structural applications of MgO are possible, such as a flooring underlayment or for bracing walls. Unlike drywall or glass matt-faced gypsum boards, MgO-made boards are not entirely homogeneous but do not have a separate facing. Delamination is, therefore, not a problem because the material is solid in all practical senses.
Electrical (Insulating Material)
In its purest form, magnesium oxide powder (MGO powder) is a white powder consisting mainly of magnesium. In a variety of temperature sensor types, including mineral-insulated thermocouples, it serves as an insulation material. The temperature sensor wires are shielded and given electrical resistance by a densely packed magnesium oxide powder. As it is able to deal with extreme temperatures, it is now regarded as the industry standard for powder insulation for temperature sensors.
Fiber Glass Manufacture (Decorative/Special Purpose)
Glass fibers are also made with the help of magnesium oxide. For glass fibers to stay intact, they must have a high melting viscosity to ensure they do not break. When magnesium oxide is added to the glass melt, it creates a precise mold by increasing the viscosity of the melting glass. Fiberglass is mostly used in goods made of fiberglass-reinforced plastic, such as showers, tubes, and other decorative accessories.
Leather Tanning
Magnesium oxide basifying agents are often used in the tanning process of leather all over the world. This product’s function in the basification process and its significance at the conclusion of chrome tanning are well recognized. Despite being a basic chemical, magnesium oxide is a complicated substance. Despite having relatively similar chemical compositions, varied processing methods, production sources, and end-use requirements lead to the fabrication of highly distinct physical properties. Reactivity is the primary aspect to be checked in quality control from the perspective of chrome tanning, and the major type of MgO employed is the low-reactive form. The chemical composition, surface area, and particle size distribution of the product are what, in this situation, determine reactivity.
Paper and Pulp
The use of magnesium oxide in the pulp and paper industry enables mills to boost process effectiveness and profitability in areas like pulp cooking and chlorine-free bleaching of pulp. Magnesium oxide is utilized in lieu of ammonia water in alkaline buffer and ammonium sulfite pulping, and the indices of the slurry can match those of the ammonia water technique. Magnesium as a buffer makes pulp simple to bleach, encourages the process of lignin distillation, lowers pollutant emissions, helps to protect the environment, but also lowers expenses. When bleaching pulp, magnesium oxide is employed. Magnesium oxide can take the place of caustic soda in the conventional bleaching procedure.
Refractory (Ceramics/Steel Industry)
High temperatures (over 1,000°F or 538°C), which are typical of many manufacturing processes, may be tolerated by refractory materials. They aid in maintaining heat-intensive industrial operations. Magnesium oxide (MgO) is the preferred refractory material for heat-intensive metal, glass, fired-ceramic, and steel industry applications due to its unique qualities as a refractory material, as well as its widespread availability and reasonable price. Magnesium oxide doping in ceramics efficiently reduces grain development and increases fracture toughness.
Waste Water Treatment
Magnesium oxide is replacing caustic soda and lime in wastewater treatment procedures, notably the nitrification and anaerobic digesting ones. When water has a pH of between 7 and 8, which is neutral or slightly alkaline, bacteria and other organisms engaged in wastewater treatment perform at their best. Alkali typically has to be added to the water in order to keep the pH at its ideal level. In wastewater treatment plants, magnesium hydroxide slurry can be used as a source of alkalinity and biological treatment. Magnesium provides the bacteria with nutrients, and the slurry’s capacity to function as a buffer raises the pH of the water.
Oilfield Industry and Mining
The properties of the drilling muds and mining, which contain several additives, must be thoroughly understood in order to perform drilling operations. Their intricate makeup can alter the fluid’s alkalinity, rheology, or density. Magnesium can make it possible to control these variables. It functions as a scouring agent in brine drilling mud, keeping the annulus clean. Additionally, it aids in balancing out the drilling process’s acidic gas emissions. Magnesium can be used to modulate fluid alkalinity, especially in clay-free polymer-based fluids. Attapulgite can also be used to control the rheology of drilling mud. Higher fluid viscosity is possible when just trace amounts (about 2% by weight) of magnesium oxide are used.
Regional Analysis of Magnesium Oxide in the Market
The market for caustic calcined magnesia is predicted to expand steadily in Asia Pacific. In order to gain a competitive advantage over its counterparts, the chemical industry has had to expand its operations. The top nation is China. The North American cosmetics market will rise as a result of growing product uptake. The rise in Europe is a result of the expanding demand for goods in the building sector.
