Light Magnesium Oxide and Heavy Magnesium Oxide

Light magnesium oxide Properties: Light magnesium oxide is white, amorphous powder, odorless, tasteless and nontoxic, with specific gravity of 3.58(25), melting point of 2852 and boiling point of 3600. Uses: Used in metallurgy, smelting, manufacturing of high-grade magnesium bricks, refractory materials and moisturizing materials, and also widely used in rubber, rubber sheets, rubber products, pharmaceutical industry, food industry, plastic sheet accelerator, plasticizer of glass fiber reinforced plastic and surface coating paint of silicon steel sheets, paper production, steel ball polishing, leather treatment, insulating materials, grease, dyes, ceramics, desiccant, resin, flame retardant, etc. magnesiumoxide,heavy Main ingredients: It is made by calcining magnesite to remove impurities. There are two kinds of magnesia generally referred to as light burning and heavy burning, which are heavy magnesia. Magnesium oxide mixture: composed of 60g magnesium oxide and 60g heavy magnesium carbonate. Properties: White powder; Odorless and tasteless; Can slowly absorb carbon dioxide in the air. Almost insoluble in water, insoluble in ethanol and soluble in dilute acid. Indications: The acid resistance is stronger, slower and longer than that of sodium bicarbonate, and does not produce carbon dioxide. It reacts with gastric acid to generate magnesium chloride and release magnesium ions, which stimulates intestinal peristalsis and has laxative effect. It is suitable for patients with hyperacidity and gastric and duodenal ulcer with constipation. For those without constipation, its laxative effect can be corrected by taking calcium carbonate together.
