What is light burned magnesia powder, heavy burned magnesia powder and light magnesia ball?

The calcined magnesite is calcined and melted at different temperatures, and the main component is Magnesium Oxide calcined magnesia, heavy burned magnesia and fused magnesia.

Magnesite calcined at 750-1100 temperature is called "light burn". Its product is called light burned magnesia powder, or referred to as light burning powder. Light burned magnesia powder is mainly used to make cementing materials, thermal insulation and sound insulation building materials, and can also be used as ceramic raw materials.

Heavy burned magnesium powder is mainly made of light burned powder, and is prepared by water separation, hydrolysis, solid-liquid separation, drying, calcination and grinding. The production of heavy Magnesium Oxide has high quality requirements for light burned magnesia powder. Generally, high-grade magnesia powder produced by high quality magnesite should not be lumped by damp.

Light magnesia ball

Light burned magnesia powder, short for light magnesia powder, is a kind of activated Magnesium Oxide obtained by calcining of magnesite, brucite and magnesium hydroxide extracted from sea water or brine through calcining at about 800~1000. Light burned magnesia powder is light yellow, light brown powder, the size of most of the grain is below 100 mesh, periglast crystal is very small, the density is 3.07~3.22g/cm3, the lattice constant is large, the lattice defect is large, the lattice defect is many, the texture is brittle, the structure is porous, the reaction activity is very large, the solid state reaction or sintering is easy to be carried out, and the action of water is formed to harden the Mg (OH) and bond energy.
