Magnesium Oxide
| Chemical Name: | Magnesium Oxide | |
| Molecular Formula: | MgO | |
| Molecular Weight: | 40.3 | |
| CAS: | 1309-48-4 | |
| Character: | Fine white powder. No smell. Because of the different preparation methods, there are light and heavy quality. Strong refraction in the visible and near ultraviolet range. Exposed to the air, it is easy to absorb water and carbon dioxide and gradually become basic magnesium carbonate, light and heavy faster, combined with water to produce magnesium hydroxide, a slightly alkaline reaction, and the pH of saturated aqueous solution is 10.3. However, it is highly soluble in dilute acids and very slightly soluble in pure water, and its solubility is increased by the presence of carbon dioxide. Insoluble in ethanol. Relative density (d254)3.58. Melting point 2852℃. Boiling point 3600℃. | |
| Uses: | 1, used as food additives, color stabilizer, in food processing can be used as sugar refining decolorization agent, PH regulator of ice cream powder, etc., so that our food looks better and tastes more delicious; 2, used as sugar refining bleaching agent ice cream powder PH regulator. 3, as an anti-caking agent and antacid agent used in wheat flour, milk powder chocolate, cocoa powder, grape powder, powdered sugar and other fields, can also be used in the manufacture of ceramics, enamel, glass, dyes and other fields. 4, as health care products, food supplements of magnesium. Also widely applied in functional health care products such as: calcium, magnesium, magnesium nutrition agent, food additives |

| Packing: | It is packed with plastic bag as inner layer, and a compound plastic woven bag as the outer layer. The net weight of each bag is 25kg. | |
| Storage & Transportation: | It should be stored in a dry and ventilative warehouse, kept away form water and moisture during transport, unloaded with care so as to avoid damage to bags. Furthermore, it should be stored separately from poisonous substances. | |
