Product Description

Calcined kaolin for Ultramarine

Benefits and Application:

It is a dehydroxylated aluminum silicate produced at a controlled temperature heating of a water-fractionated kaolin. It was specifically designed for Ultramarine.
1. It is produced at low temperature and by a rapid calcination process in rotary kiln, can improve the ultramarine coloring power, due to better activity of metakaolin.
2. It can greatly improve the acid resistance of Ultramarine products due to its high purity, low impurity content.
3. It has better sintering properties, because its raw material is raw ore of coal kaolin blending with natural kaolin ore.
