2. Molecular Formula: MgCO3
3. Molecular Weight: 84.31
4. CAS: 546-93-0
5. Character: In normal temperature, it's with three hydrates. Light one is white, easily fragile or loose white powder. Odorless. Relative density is 2.2. Melting point is 350ºC. It's stable in the air. When heated to 700ºC, it will become magnesium oxide. It's hardly soluble in water, but it'll bring a slight alkaline reaction. It can not be soluble in ethanol but it could be soluble in olefine acid with sparkling.
