Potassium pyrophosphate is a potassium pyrophosphate, which is a colorless crystal or white powder. Has hygroscopicity in the air. Its properties are similar to those of sodium pyrophosphate, but its solubility is relatively high. Soluble in water, insoluble in ethanol.

Application
Mainly used for cyanide free electroplating, replacing sodium cyanide as a complexing agent for electroplating. It is also used as a pre-treatment agent for electroplating and as a pyrophosphate electroplating solution. Preparation of laundry detergent components, metal surface cleaning agents and bottle cleaning agent components, and additives for various cleaning agents. Used as a clay dispersant, pigment and dye dispersant, and buffer in the ceramic industry. The bleaching and dyeing industry is used to remove small amounts of trivalent iron ions from water and improve the quality of bleaching and dyeing.
