Common questions about Kaolin Clay Powder
Kaolin powder is used in ceramics, tiles, refractory bricks, foundry molds, rubber and plastic fillers, and construction materials due to its fine particle size, whiteness, and thermal stability.
Typical kaolin contains 45–55% SiO2 and 35–38% Al2O3 with purity ranging from 95 - 99% and very low impurity levels.
For ceramic bodies and tiles, kaolin with D50 between 0.7 - 3.5 µm and D90 below 10 µm provides good plasticity, packing density, and firing behavior.
Yes. With a melting point of 1750 - 1785 °C, good dimensional stability, and low thermal conductivity, it is suitable for refractory bricks and kiln furniture.
We supply kaolin powder in 25 kg HDPE bags, 50 kg PP bags, and 1 MT jumbo bags for domestic and export shipments.
Kaolin Powder, also known as China Clay, is a fine hydrous aluminosilicate clay primarily composed of kaolinite. It is widely used as a plasticizer, filler, and refractory raw material in ceramic bodies, tiles, refractories, foundry molds, rubber compounding, and construction materials.
Green Trade India supplies industrial grade kaolin powder with controlled particle size, high whiteness, low impurity levels, and stable rheological behavior. Our material is suitable for both domestic manufacturing and export applications, offering consistent quality and reliable bulk supply.
