Washed Kaolin

Washed Kaolin

Washed Kaolin (also known as China Clay) is an essential mineral raw material for ceramic production. Our water-washed kaolin features low iron and titanium content, stable chemical composition, good plasticity and high whiteness. It is widely used as raw material for ceramic bodies and ceramic glazes, improving green body strength, reducing shrinkage and enhancing glaze surface performance.

Washed Kaolin Clay for Ceramics/Ceramic Kaolin Raw Material

We supply premium washed kaolin powder for tiles, porcelain, tableware and art ceramics. Supported by stable mineral sources and refined beneficiation processes, each batch comes with complete test reports to guarantee consistent quality. We can customize particle size and indicators according to customers' formulation requirements. We offer reliable ceramic mineral raw materials and professional ceramic formulation technical support.

FAQ

 

 

01.Why use washed kaolin for ceramic bodies?

A: Washed kaolin provides excellent plasticity for forming. It supplies Al₂O₃ to build the skeleton of green bodies, improve green strength and reduce breakage during handling. It also lowers drying cracking risk and delivers clean base color after firing.

02.What is the function of washed kaolin in ceramic glaze?

The standard of sprockets can be determined according to different application requirements. The difference between metric sprockets and sprockets built to ANSI standards is that they use different units of measurement for chain specifications.

03.Features of high whiteness washed kaolin?

A: Low iron and titanium content for high fired whiteness. Purified by water washing with few coarse impurities. Stable chemical composition and consistent batch quality. Fine powder, good plasticity, ideal for white ware and light-colored glazes.

04.Notes for washed kaolin powder used in tiles?

Control dosage to avoid excessive drying shrinkage and cracks. Watch LOI (loss on ignition); fast heating may cause pinholes. Match particle size for ball milling and spray granulation. Keep Fe₂O₃ & TiO₂ low to prevent dark spots. Run lab trial before mass production.

05.Why is washed kaolin widely adopted for tableware & porcelain?

Water-washed kaolin has low impurities and high fired whiteness. Great plasticity for thin-wall tableware forming. Alumina support reduces deformation during firing. It produces dense smooth body and clean glaze for mass production of porcelain.

06.Secret of ceramic firing: Kaolin for glaze (China Clay)

Glaze kaolin is a key mineral raw material matching ceramic frits. It keeps glaze slurry stable and uniform coating. In high-temperature firing, alumina controls glaze melt viscosity to stop glaze running, pinholes and crawling. Quality glaze kaolin is essential for smooth, clean glaze surface.
