Synthetic Magnesite

Characteristics

* Synthetic magnesite consists of cubic crystals of uniform particle diameter and has a sharp particle size distribution.
* Synthetic magnesite is pure anhydrous magnesium carbonate and, since it contains no crystal water, it is excellent in heat stability and stable up to about 500oC.
* Synthetic magnesite consists of heavy powders with low specific surface area and is excellent in flowability.
* Synthetic magnesite has a low specific gravity and relatively high heat conductivity for an inorganic material, and it can be used as a heat emission filler.
* Since the crystal of synthetic magnesite is soft, it causes little abrasion in molds when used as a filler.
