Description
1. Function:
It is white single crystal or amorphism powder with no smell and no poison, nearly tasteless, it is stable in the air, its relative density is 2.1. It is slightly soluble in water; its aqueous solution is alkaline. Its water solubility is 1.02 %( 15? C), easily soluble in acid and ammonium salt solution. It reacts with acid to decompose carbon dioxide. Heated up to 300? C, it decomposes into carbon dioxide and magnesium oxide. USP22/CP95/CP2000, HG/T 2959-2000.
2. Application :
Mainly used as intermediate substance of pharmaceutical products, decomposer of acid liquor, desiccant, color protection liquor, carrier, anti- agglomeration liquor; It also used as additive for food, supplement of magnesium element. For rubber industry, it is used as ancillary substance and filler; it can be used as adiabatic, heatproof, fire proof and heat preservation material. For high-level glass product, ceramics, chinaware, it can increase their brightness of the surface. It can be used for magnesium salt pigment, paint, cosmetic, ship manufacture, and boiler and so on.
