Specifications

Tetra Potassium Pyrophosphate

Molecular Formula: K4P2O7

Molecular weight: 330.34

 

Properties:

Anhydrous tetra potassium phosphate is in white powder. Relative density 2.3534 and melting point 1109°C; It is apt to absorb humidity in the open air to deliquescent; Soluble in water but insoluble in ethanol, and at 25 ,its solubility in water is 187g/100g water; It can chelate with alkaline metals ions or heavy metal ions.

 

Uses : It mainly applied to electroplating without cyanate, industrial or household detergents; It can used as a buffering reagent as well as stabilizer for hydrogen peroxide; It can also be used as dispersion agent for ceramic, clay, latex and pigments etc. Packing and storage:

Water-soluble, colorless crystals; dehydrates below 300.C, melts at 1090.C; used in tin plating, china-clay purification, dyeing, oil-drilling muds, and synthetic rubber production. Also known as normal potassium pyrophosphate, tetrapotassium pyrophosphate.

Potassium pyrophosphate has excellent chelating capability. It can form stable chelates with Ca2+ and Mg2+ in hard water to soften hard water, to increase washing capability, to remove dirt, and to form a layer of protection film on metal (like iron and other metals) surface preventing surface corrosion.  P2O74- has strong dispersion capability to micro-dispersed solids, enabling homogenous mixture of tiny and fine matters.  Its stable pH buffer capability maintains long-term solution pH value. Product is easy to dissolve in water, its solubility is 187 g/100mL at 25.C.

Packing: 25kg woven bag
