FERROUS SULPHATE HEPTAHYDRATE FOR CHORMIUM REDUCTION CHEMICAL ANALYSIS : ITEM INDEX FeSO4.7H2O >98 Fe >19% As%

It is used in synthetic fiber industry, preservative, material of printing and dyeing and be used in medical for fungicide and emetic, and in electroplate, water purifiction etc.

Ferrous sulfate is a blue-green chemical used in many applications including medicine, ink and dye manufacturing, as well as agriculture. It can be found in various states of hydration, and several of these forms exist in nature. These are the more common mineral forms: FeSO4 -7H2O (Melanterite, blue-green)

Introduction Product Name:Ferrous Sulphate Heptahydrate CAS No:7720-78-7 Formula:FeSO4 ·7H2O Formula Weight:278.05 Assay:98% Fe: 19.8% Insoluble matter: 0.5% Application Ferrous Sulphate Heptahydrate on cement and concrete has a retarding effect, less alone play a role and most of the other retarding agent, and most of the other retarding agent compound for additives or synergistic agent. Ferrous Sulphate FeSO4�·7H2O which contains divalent iron (Fe2+) acting as efficient element for reducing harmful hexavalent chromium (Cr6+) to trivalent one (Cr3+) is the most used raw material for decreasing hexavalent chromium in praxis. Adding 98% Ferrous Sulphate Powder FeSO4·7H2O into cement will not affect the product property such as bending strength, compressive strength and water solubility etc. Method of use Add about 900PPm Ferrous Sulphate Heptahydrate in the production process of cement magnesium chromium mud, can reduce the hexavalent chromium in cement to 2ppm, and the reduction performance is quite stable. If it is the super chromium cement that has been produced, we can still add ferrous sulfate to mix and use it together, and it can also have a certain removal effect on chromium salt. It is believed that the use of ferrous sulfate will bring health to more people.

Introduction Product Name:Ferrous Sulphate Heptahydrate CAS No:7720-78-7 Formula:FeSO4·7H2O Formula Weight:278.05 Assay:99.4% Application In the production of ceramic frit,99.4% Potassium Nitrate KNO3 is mainly to provide potassium, its main role is to reduce the melting temperature,but also increase the expansion coefficient of the frit,but also conducive to increase the transparency of the frit,potassium high temperature viscosity is large,has the role of expanding the glaze sintering range.At the same time, due to the role of nitrate,it will decompose at high temperature to produce oxygen,so it also has oxidation,which is conducive to improving the whiteness of the frit. In addition,Potassium Nitrate NOP Granular or Powder is applied in TV glass,glass refining agent and motor light glass,fertilizers of crops and flowers,leaf spraying fertilizer,fireworks and black powder,drugs and catalyzer,ceramic and enamel.
