Molecular formula: 3MgCO3· Mg(OH)2· 3H2O
Physicochemical properties: white monoclinic crystal or amorphous powder. The composition is generally represented by x MgCO3· y Mg(OH) 2 · z H2O. There are several ratios of x, y, and z, which can be 4:1:4, 4:1:5, 4:1:6, 4:1:7, 3:1:3, 3:1:4. Non-toxic, tasteless, stable in the air. The relative density is 2.16. Slightly soluble in water, the aqueous solution is weakly alkaline. The solubility in water is 0.02% (15 ° C). Soluble in acid and ammonium salt solution, in case of dilute acid, it will release carbon dioxide. When heated to above 300 ° C, it decomposes to form water, carbon dioxide and magnesium oxide.
