Burned Magnesia is a refractory material made by calcining natural magnesite or synthetic magnesia at high temperature. Its performance mainly depends on the purity of the raw materials and
the calcination temperature. It is usually widely used in the fields of metallurgy, building materials and chemical industry.
85%-92%Dead burned magnesia is mainly made of natural magnesite ore with 46%content,which is calcined by high temperature kiln at about 1400℃-1800℃ .
94%-98%Dead burned magnesia is made of natural super-grade magnesite ore. It is made by light burning, fine grinding, pressing balls and calcining in ultra-high temperature oil shaft kiln.
Compared with Fused Magnesia, Sintered Magnesia has lower density and corrosion resistance, but lower cost, and is suitable for medium-high temperature and non-corrosive environments.
Compared with Large Crystal Fused Magnesia, its crystal particles are smaller and its performance is slightly inferior, but it strikes a balance between cost and temperature resistance, and is
more economical.

Application of Burned magnesia:
Steel industry: used to produce alkaline refractory bricks (such as magnesia bricks, magnesia-chrome bricks) and linings of steelmaking converters, electric arc furnaces, etc.
Cement industry: often used as lining materials for high-temperature rotary kilns to increase the life of kilns.
Nonferrous metal industry: used as refractory materials for smelting furnaces such as copper, aluminum, and zinc to ensure the stability of the furnace lining.
Chemical industry: used as refractory lining materials for industrial chemical equipment to adapt to high-temperature corrosive environments.
Other fields: used to manufacture insulation materials, castables, and refractory powders in alkaline environments.
