A white, yellowish or brown crystalline solid used in the manufacture of refractories. Contact with water is unlikely to harm this commodity, as the tendency would be to wash away impurities.
Magnesite can be used as a slag former in steelmaking furnaces, in conjunction with lime, in order to protect the magnesium oxide lining. It can also be used as a catalyst and filler in the production of synthetic rubber and in the preparation of magnesium chemicals and fertilizers.
Similar to the production of lime, magnesite can be burned in the presence of charcoal to produce MgO, otherwise known as periclase. Such periclase is an important product in refractory materials. Magnesite can also be used as a binder in flooring material.
In fire assay, magnesite cupels can be used for cupellation as the magnesite cupel will resist the high temperatures involved.
Dead burned magnesite is selected from natural magnesite, it is produced by mine-selecting, purifying, calcining in shaft kilns. It is an ideal material for unshaped refractory material, the final products are used in opening hearth furnace, electric furnace bottom furnaces lining tamping. Dead burned magnesite (middle grade) is made from sorted natural raw magnesite through sintering in high temperature shaft kilns. They are ideal materials for making monolithic refractories. Their finished products are also used for making the bottoms or lining of open-hearth furnace and electric arc furnace.
