Molecular Formula | CMgO3
|
Molar Mass | 84.3139 |
Physical and Chemical Properties | This product is hydrated basic magnesium carbonate, magnesium oxide content is 40.0%~ 43.5%, white powder, non-toxic, odorless, almost tasteless. It is stable in the air, almost insoluble in water or ethanol, but can make the water weakly alkaline. It dissolves by releasing carbon dioxide in dilute acid. Above 300 ℃, it decomposes, releases water and carbon dioxide, and generates magnesium oxide. |
重质碳酸镁(药用碳酸镁) - Introduction
Heavy magnesium carbonate, also known as medicinal magnesium carbonate, is an inorganic compound composed of magnesium ions and carbonate ions, with the chemical formula MgCO3. The following is the introduction of heavy magnesium carbonate properties, uses, preparation and safety information:
Nature:
1. Appearance: colorless or white crystalline powder.
2. Solubility: Slightly soluble in water, but easier to dissolve in acidic solution.
3. density: the relative density is high, about 2.96-3.17g/cm³.
4. melting point: melting point is about 310-330 ℃.
Use:
1. Medicinal field: Heavy magnesium carbonate is commonly used as an active ingredient in drugs, which has the effects of relieving gastric acid reflux, treating indigestion and relieving constipation.
2. cosmetics and skin care products: heavy magnesium carbonate is widely used in cosmetics and skin care products, can be used as an important component of foundation, skin care lotion and mask. It can absorb oil, regulate skin oil secretion and provide gentle skin care effect.
3. Food industry: Heavy magnesium carbonate can be used as a food additive, adjust pH, and as an ammonia source for yeast.
Preparation Method:
1. Magnesium carbonate can be prepared by reacting carbon dioxide with magnesium hydroxide. Carbon dioxide is dissolved by climatic groundwater to form magnesium bicarbonate and magnesium hydroxide to react to form heavy magnesium carbonate.
2. Heavy magnesium carbonate can also be prepared by reacting magnesium sulfate with sodium carbonate.
