Magnesium carbonate, basic magnesium carbonate

Magnesium carbonate, Basic Magnesium carbonate

At room temperature, it contains three hydrates. The light-colored form is white, brittle, or loose white powder. Odorless. Relative density is 2.2. Melting point is 350°C. It is stable in air. When heated to 700°C, it turns into magnesium oxide. It is almost insoluble in water but causes a slight alkaline reaction. It is insoluble in ethanol but soluble in oleic acid with effervescence.

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.
