Product Manufacturing

Production Condition: explore from natural underground magnesite mine.

 

Application in ceramic industry

Hard-burned magnesium obtained by calcining magnesite at 1400 ~ 1800 ℃, and then molten magnesium oxide or fused magnesium oxide by calcination at 2500 ~ 3000 ℃, which has good stability, high hardness and strong chemical resistance 、 High resistivity and almost no chemical reaction with water and other characteristics, used as insulation and advanced refractory materials, making magnesium crucibles and refractory furnace tubes, etc. Utilizing the low thermal expansion coefficient of lightly burned magnesium, it is used as a calcined mixed material in the ceramic industry. Ceramic products and high-temperature-resistance. High-strength ceramic parts required for the manufacture of cutting-edge defense industries, such as high-temperature-resistant special ceramic sheets for jet aircraft and rocket combustion chamber nozzles. 

 

Application in building materials industry

Magnesite is used as a binder in the building materials industry. Magnesite can be made into magnesium-containing cement (called Solair cement). This cement has high cohesiveness and plasticity, and its setting time is short. The organic substance has a strong binding force, and it is very hard and beautiful in color after hardening. It is suitable for building decoration; while it is used as a building materials, it has good thermal insulation, sound insulation, thermal insulation and grinding performance, and its hardness and elasticity are better than ordinary cement; light burnt magnesium add appropriate amount of sawdust, wood chips, sand, etc. to make floors, step boards, particle boards, foam cement, magnesium-containing plaster, paints, artificial grindstones and grinding wheel cement, as well as stone, slate, stone walls, stone columns, artificial marble and other buildings Materials and decorative materials are widely used in house construction.
