About Products

The production of ceramics demands a depth of expertise, dedication, and premium-quality raw materials often underestimated by many. Among the most valuable raw materials in ceramic manufacturing is sodium tripolyphosphate (STPP). This organic compound, also known as STPP, plays a pivotal role in various aspects of ceramic production.

STPP serves as an effective agent for reducing the viscosity of glazes, facilitating smoother application and enhancing the finish of ceramic products. Additionally, it demonstrates exceptional chelating properties, capable of binding with hard metal ions present in the production process, thereby optimizing the quality of the final ceramic output. Moreover, STPP exhibits excellent degumming effects, contributing to the refinement and purification of ceramic materials during production.

The primary application of sodium tripolyphosphate (STPP) in ceramic production lies in its capacity to decrease the viscosity of a mass or slurry, thereby enhancing the fluidity of the desired material. This capability proves invaluable in several ways.

Firstly, by reducing viscosity, STPP contributes to improved flow properties, facilitating more efficient processing of ceramic materials. This increased fluidity can lead to cost savings, as any reduction in water content helps to decrease energy consumption during operations such as ball milling or spray drying. Additionally, the enhanced fluidity achieved with STPP can result in smoother application and more uniform distribution of ceramic materials, ultimately improving the quality and consistency of the final products.
