Sodium Polyphosphate (STPP)

Description

Sodium Polyphosphate, or STPP, is an inorganic compound with the chemical formula Na5P3O10.
Sodium Triphosphate is an important additive in the preparation of ceramic raw materials. It not only solves the problem of mud but also reduces production costs.

STPP is currently in great demand as a high-performance water-reducing agent in the ceramic field.
Pentasodium Triphosphate also is an additive commonly active in building sanitary ceramics, which can improve ceramic glazes’ performance and play an essential role in ceramic production.

Sodium Tripolyphosphate served as a dispersive additive in ceramic mud. Although the dosage is small, it often plays a prominent role in energy saving, new product development, and new process creation.

Sodium Polyphosphate (STPP) has an excellent performance in integrating complex metal ions and has a good degumming effect in ceramic production. So Na5P3O10 has been used as an additive in ceramic glazes for a long time. Thus, what are the benefits of adding a Sodium Tripolyphosphate debonding agent?

1. Reduce the mud’s moisture content and increase the mud’s fluidity.
2. Sodium Polyphosphate shortens the grouting time, reduces the shrinkage rate, and reduces the deformation of the green body.
3. Increase the suspension of the mud so that the raw material particles are not easy to settle.
4. Makes the green body easy to de-mold, thereby reducing the cracking of the green body.

Therefore, (STPP) Sodium Polyphosphate is also a nickname for a water-reducing agent, debonding agent, and decoagulant in ceramic production. Its function is mainly to improve the fluidity of the ceramic body and glaze slurry so that the slurry has the least moisture, better fluidity, no flocculation, and precipitation, and is easy to operate.
