Supply dragon chemical RL-001 lightweight magnesium oxide

A lightweight magnesium oxide, magnesium light performance: lightweight magnesium oxide is light loose white amorphous powder. Odorless, non-toxic. Lightweight share is about three times the normal volume of about heavy magnesium oxide. Exposed to the air easily absorb moisture and carbon dioxide, insoluble in water and alcohol, soluble in dilute acid to form the corresponding magnesium salt solution. Magnesia highly refractory insulation properties, a specific gravity of 3.58 (25), a melting point of 2852, the boiling point of 3600, slightly soluble in water and organic solvents, can be dissolved in acid or salt solution. Formula MgO, molecular weight 40.31 Second, lightweight magnesium oxide Uses: Can be used in metallurgy, smelting, senior magnesia, refractory materials manufacture and moisturizing, also widely used in the rubber industry, rubber products, pharmaceutical industry, food industry, plastic sheets to promote agents, plasticizers and silicon FRP surface coating of paint, paper fillers and reinforcing agents produced, ball polishing agents, leather treatment, insulating material, oil, dyes, ceramics, drying agent, the resin, flame retardant agents used rubber products, fillers and reinforcing agents, soft ferrite, adhesives, chemical industry as a catalyst and the manufacture of other magnesium compounds, enamel, ceramics, glass and other raw materials because professional, so good.
