We are engaged in manufacturing, distributing and supplying Magnesium Sulphate Heptahydrate, comprises of magnesium, sulfur and oxygen. The Magnesium Sulphate Heptahydrate has a pH of 6 in its hydrated form and it is commonly known as Epsom salt. The anhydrous Magnesium Sulphate Heptahydrate is hydroscopic, therefore it is difficult to weigh. Used as a drying agent, the anhydrous Magnesium Sulphate Heptahydrate is used for medical preparations. Chemical Formulae : MgSO4 7H2O Applications : To correct magnesium deficiency in soil, since magnesium is an essential element in the chlorophyll molecule Potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, peppers and As a component of bath salts Specifications : Purity as MgSo4 7H2O < 99% to 99.5% Magnesium Sulphate as MgSo4 < 48.5% Magnesium Oxide as MgO < 16% to 17% Magnesium as Mg < 9.6% PH of 5% aqueous solution < 7 + 0.5 Sulphates of K and Ca > 0.1% each Chlorides of K and Ca > 0.1% each Chlorides of Cl > 300 ppm Heavy metals as Pb > 2 ppm Arsenic as As2o3 > 2 ppm Iron as Fe > 20 ppm Calcium as Ca Octyldecylamin > 300 ppm 0.01% (100rpm)
