100 mesh --325 mesh of magnesium calcium powder

It has the characteristics of small particle size, narrow particle size distribution, little impurity, good insulation, low oil absorption value and high whiteness. It is widely used in plastics, rubber, building materials, coatings, glass, fertilizer, chemical industry, textile, composite materials and so on.
Our factory sells all kinds of Magnesium Oxide (light burning powder, magnesia calcium powder), light burned magnesia ball, concentrate ball, heavy burned powder, fused magnesia, high purity magnesia, ordinary magnesia and talc.
Light burning powder
Magnesium Oxide (MgO) is commonly referred to as magnesite, light burned powder and magnesia powder. The density is 2.94, white powder. The melting point is 2852 centigrade, and the boiling point is 3600. It is soluble in acid and ammonium salt, which is difficult to dissolve in water and ethanol. The specific surface area of the calcined temperature at 400 C is 180m2/g. At 1300 C, the specific surface area is only 3m2/g. Easy deliquescence in the air. It belongs to the pneumatic cementation material.
Electrofusion magnesia
Fused magnesia is made of magnesite after electrofusion. It has the characteristics of complete structure, good chemical stability and high temperature strength. It is a high-grade alkaline refractory material used in metallurgy, building materials, chemical industry, national defense, scientific research, medical equipment, household appliances and so on.
Fused magnesia is made from selected grade a natural magnesite or high-purity light burned magnesia particles and melted in an electric arc furnace. The product has high purity, large crystalline grain, compact structure, strong slag resistance material and good thermal shock stability. It is an excellent high temperature electrical insulating material. It is also an important raw material for making high-grade magnesia brick, magnesia carbon brick and amorphous refractory.
High purity magnesia
High purity magnesia is a natural special grade magnesite ore, which is made of light burning, fine grinding, ball making and ultra high temperature shaft kiln. It is a high quality raw material for making bricks and unshaped refractory materials.
