Industrial grade Potassium pyrophosphate 7320-34-5 (K4O7P2) uses Price
Potassium pyrophosphate, also known as tetrapotassium pyrophosphate, is produced by the melting of potassium dihydrogen phosphate to lose water molecules. It is a white crystalline powder or granule at room temperature. It has strong hygroscopicity in air and is highly soluble in water. However, it is insoluble in ethanol, and the aqueous solution is alkaline, which inhibits food spoilage and fermentation.
It is often used in combination with other condensed phosphates. In order to make the plating layer smooth and firm, the formulation of the plating solution in industrial production is often complicated. In the past, cyanide was commonly used as a complexing agent to prepare a plating solution. However, due to the high toxicity of CN-, the health of electroplating workers is greatly damaged. At the same time, the discharge of sewage and exhaust gas containing CN- also seriously pollutes the environment. Therefore, electroplating is now mainly used for cyanide-free plating, and this complexing agent for r
