General Description:

Sodium tripolyphosphate (STPP) is an organic compound which is ideal for decreasing the viscosity of glazes, chelating hard metal ions, and also has an excellent degumming effect in ceramic production. It is typically supplied as a white powder or granular product which must be kept dry in a well-ventilated place, away from extremes of heat and cold. The primary use of STPP in ceramic production is through its ability to lower the viscosity of a mass or slurry and in doing so improve the fluidity of a desired material. This can reduce costs, as any reduction in water content helps to lower energy consumption in a ball mill or spray drying tower (spray column).
