Other English Name
Magnesium carbonate hydrate,Magnesium carbonate;Magnesia carbonica;UNII-0E53J927NA;Magnesium carbonate [II];Magnesium carbonate hydrate;Magnesium carbonate,light;Magnesium carbonate,heavy;Magnesium carbonate (TN);Magnesium carbonate,N-hydrate;
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 350℃. It’s stable in the air. When heated to 700℃, 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.
