2. Chemical property

Stability: stable at 48.1 degrees Celsius in humid air, easy weathering in warm and dry air, is higher than 48.1 DEG C, losing 1 to become the six Magnesium Sulfate crystal water, water, at 67.5 DEG C, soluble in the water of crystallization, and the precipitation water Magnesium Sulfate, at 70 to 80 DEG C, lost 4 crystal the water lost 5 crystal water of 100 DEG C, losing 6 crystal water at 150 DEG C, lost all crystal water at 200 DEG C, become anhydrous powder Magnesium Sulfate, dehydrated material placed in moist air to re absorb water. Magnesium Sulfate in the saturated solution, can crystallize respectively with 1, 2, 3, 4, 5, 6, 12 water hydrate crystals, in -3.9 to 1.8 DEG C saturated aqueous solution, precipitation of twelve water in Magnesium Sulfate, -1.8 to 48.18 DEG C saturated water solution, precipitation water in 48.1 ~ seven Magnesium Sulfate. 67.5 DEG C saturated aqueous solution, precipitation of six water is higher than 67.5 degrees Magnesium Sulfate, a Magnesium Sulfate six precipitation water, water Magnesium Sulfate incongruent melting at 87 to 92 DEG C, and generate five or four water water Magnesium Sulfate, Magnesium Sulfate four water at 106 DEG C into Sanshui Sanshui Magnesium Sulfate, Magnesium Sulfate in the 122 to 124 DEG C two Magnesium Sulfate two Magnesium Sulfate water, water in a water Magnesium Sulfate 161 to 169 DEG C into stable.

Product Application
