What are light burnt magnesia powder, heavy burnt magnesia powder and light burnt magnesia ball?
Light burnt magnesite powder can be calcined and melted at different temperatures to produce light burnt magnesia, heavy burnt magnesia and fused magnesia with the main component of magnesia.
Magnesite calcined at 750-1100 temperature is called "light burning". Its product is called light burning magnesia powder, referred to as light burning powder. Light burnt magnesia powder mainly produces cementitious materials, thermal insulation and sound insulation building materials, but also can be used as ceramic raw materials.
Heavy-burned magnesium powder is mainly made from light-burned powder by water separation, hydrolysis, solid-liquid separation, drying, calcination and crushing. The production of heavy magnesia requires high quality of light-burned magnesia powder. In general, high-grade magnesite powder produced by high-quality should not be damp caking.
Light burnt magnesia ball
Light-burned magnesia powder, referred to as light-burned magnesia powder, is a kind of active magnesia obtained by calcining magnesite, brucite and magnesium hydroxide extracted from seawater or brine at about 800-1000 C. Light burnt magnesia powder is a light yellow and light brown powder. Its particle size is mostly below 100 mesh. Its crystal density is 3.07-3.22g/cm3. It has large lattice constant, many lattice defects, brittle texture, porous structure and high reactivity. It is easy to react with water to form Mg(OH)2, which hardens and has bonding ability.
