Main Category:
☆ Magnesia
■ Material and Technique: Commonly called dead-burned magnesia and made in shaft kilns ■ Properties: The MgO content is typically between 91-93%. ■ Application: used as raw material for the low-grade magnesia brick and monolithic product
☆ High Quality Magnesia
■ Material and Technique: Commonly called medium-grade magnesia and made in shaft kilns ■ Properties: It has low impurity, high bulk density, and high slag resistance. ■ The main application is mid-grade magnesia brick and monolithic product
☆ High Purity Magnesia
■ Material and Technique: made in high-temperature shaft kilns ■ The MgO content is over 97% ■ Application: used for high-grade basic brick
☆ Fused Magnesia
■ Material and Technique: Use first-class magnesia or caustic magnesia fused in electric furnace ■ Properties: It is high in bulk density, slag resistance and volume stability, ■ Application: used for carbon-containing refractories and monolithic products
☆ Caustic Magnesia
■ Material and Technique: made from magnesia in reverberatory kilns ■ Properties: The MgO content is high and it has vibrant chemical activity. ■ Application: The main application is for high-grad magnesia and synthetic spinel clinker as well as in magnesia cement. It also has many applications in ceramic, construction materials and chemical industries.
