Feature in white or colorless crystal, odorless, cool, little bitter, dissolve in water easily, 2. Application: (1)magnesium is important element in chlorophyll, is necessary for photosynthesis. Magnesium is activator for many enzymes, is able to accelerate metabolism for carbohydrate, composition for nucleic acid, transform for phosphate, etc. Magnesium sulfate is very important fertilizer for its rich nutrition. Moreover, magnesium benefits for crop growth and high yield. Magnesium sulfate not only provides magnesium and sulfate element, but also loosens soil. Magnesium and other 15 elements are considered as nutrition for plant growth and high yield, as well as nutrient component and fertilizer for relative plants. Traditional fertilizer contain such nutrient content as n, p, k, which can not enhance crop yield obviously, while, medium nutrient content (ca, mg, s) and minim nutrient ingredients (zn, cu, fe, mn, b, mo and cl) become less and less. It will cause low yield of crops. It is tested that the main reason is too much exploit of magnesium from the soil. Magnesium is important ingredient for enhancing productivity and agriculture yield. So it needs compensated in time.

It is widely used in defense, medicine, chemical industry, papermaking, shipbuilding industries and so on. In building industry, it could be used for tire-board, particle board, insulation columns, railing, artificial marble, the inhalation of asbestos, common tile, wall panels and ground laying. With the advancement of science and technology, the usage of light burning magnesium block is wider. It could also be used to make civil products, packaging carton for light and heavy machinery, packaging end beam, high temperature refractory materials, and beautiful attractive bright glossing furniture. In machinery, it is also used to cast models. Magnesium oxide (mgo) is generally known as magnesite, light burning powder, as well as magnesium oxide powder. Its density is 2.94, a kind of white powder. Its melting point is 2852oc, while boiling point is 3600oc. Dissolved in acid and ammonium salt, but difficult to dissolve in water and ethanol. When calcinations temperature reaches 400oc, its specific surface area is 180m2g. When calcinations temperature reaches 1300oc, its specific surface area is only 3m2g. It is easily deliquescence in the air. It is a kind of binding cementing material.
