potassium dichromate chemical offered 

potassium dichromate (potassium bichromate) main use is as a precursor to potassium chrome alum, used in leather tanning. Potassium dichromate has been used to prepare "chromic acid" for cleaning glassware and etching materials. It is used as an ingredient in tetra potassium phosphate cement in which it retards the setting of the mixture and improves its density and texture.   potassium dichromate is a common reagent in classical "wet tests" in analytical chemistry. Potassium dichromate is used to stain certain types of wood by darkening the tannins in the wood. It is offered in technical and analytical grade. It is available in the form of red-orange powder; crystals packed in 25kg, 50kg hdpe bag. We can offer it in many grades as per the application needs in different industry sectors.
