Magnesium Sulfate

Molecular formula: MgSO4·7H2O
Annual production capacity: 10,000 tons
Molecular weight: 246.48.
Properties: White fine needle-like or oblique columnar crystals. Odorless and bitter, easy to weather in dry air. The proportion is 1.68. Easily soluble in water, slightly soluble in ethanol and glycerin. It is soluble in its own crystal water at 67.5°C. It decomposes by heat and loses four molecules of crystal water at 70-80℃. It loses all crystal water and becomes anhydrous at about 200℃.
Uses: Mainly used in the manufacture of fertilizers, leather making, printing and dyeing, catalysts, paper making, plastics, porcelain, paints, matches, explosives and fireproof materials. It can be used for printing and dyeing thin cotton cloth and silk, as a weighting agent for cotton silk and as a filler for kapok products; it is used as Epsom salt in medicine.
