Is sodium pyrophosphate used as additive in ceramic slurry

sodium pyrophosphate is used as additive in ceramic slurry, and sodium tripolyphosphate is commonly used in ceramic slurry, especially in the peptization effect of ceramic glaze.

The trait of Sodium Tripolyphosphate is white granular or powder with a density of 0.35-0.90 g/cm3 and a melting point of 622 °C. Soluble in water, the aqueous solution is alkaline. It gradually hydrolyzes into orthophosphate in water and has good ability to complex metal ions. It can complex with metal ions such as calcium, magnesium and iron to form soluble complexes. Can soften hard water.

Mainly used in ceramic production, synthetic detergents as an important additive, soap synergist and prevent the precipitation and blooming of bar soap oil. It has strong emulsification effect on lubricating oil and fat. It can be used to adjust the pH value of buffer soap, industrial water softener, tanning pre-tanning agent, dyeing auxiliary, paint, kaolin, magnesia, calcium carbonate and other industries. The suspension is used as a dispersant, a drilling mud dispersant, and the paper industry is used as an anti-oil agent.

The PH of trimerization and pyrophosphate are basically close, 9.2 ~ 10.2; It is also difficult to distinguish in appearance. The price of trimester is slightly lower, but the difference is not big.
