Industry fertilizer feed grade 80% 85% 90% 92% 97% CM Magnesium Oxide
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 |
Test Item | index | GB 9857-1988 | |
