classification |
Reagent grade Magnesium Oxide |
Formula |
MgO |
Appearance |
white amorphous powder |
Physical and chemical properties |
odourless, tasteless, non-toxic. Poorly soluble in water and organic solvents, the high temperature (above 1000 °C) burning can be converted into crystal, so the product should be sealed storage, keep dry |
Application |
reagent grade magnesium oxide is mainly used in chemical analysis reagent, also used in glue adhesion agent, soft magnetic materials and high-tech fields |
Method |
soda method, ammonium bicarbonate la |
