BizWhite has been mining, processing, and supplying high quality Kaolin products, from its reserves in Gujarat.
On recognising the high demand for this multi-usage mineral and also the shortages of high-quality kaolin, we have positioned ourselves as one of the overriding kaolin china clay manufacturers and exporters from India.
Our Kaolin clay products are immensely used in the manufacturing of ceramics, papers, colours, vitrified tiles, soap, ultramarine, and various other purposes. Translucent quality, greater strength, and bright white appearance are the unique features of our Kaolin clay lumps.
We have our Kaolin Clay available in lumps, noodles and powder form.

Kaolin (China Clay)
Kaolin is white, soft, plastic clay mainly composed of fine-grained plate-like particles. Kaolin is formed when the anhydrous aluminum silicates which are found in feldspar rich rocks, like granite, are altered by weathering or hydrothermal process
Quality of china clay varies from mine to mine in many physical aspects, which in turn influence their end use. Of particular commercial interest is the degree of crystallinity which influences the brightness, whiteness, opacity, gloss, film strength, and viscosity.
China clay is also called “kaolin”, it is one of the essential raw material for ceramic industries, china clay does not swell on adding water & alumina present in clay do not form isomorphism series with any other metallic compound.
China Clay is a clay mineral with the chemical composition AlSiO3O5(OH)3. It is layered silicate mineral. It is soft earthy, usually white in color, produced by the chemical weathering of Aluminium Silicate mineral like Feldspar. Commercial grades of China Clay are supplied and transported as dry powder form, semi dry noodle form or as slurry.
Applications:
- It is used in Cer/bamics for body & glazing of Tiles and Sanitary Wares.
- In paper it is used as filler. It is also used for paper coating purpose.
- It is used in paint also to extend Titanium Dioxide (TiO2) and modify gloss level.
- It is used in rubber to enhance reinforcement properties.
China clay belongs to the group of Minerals called Kaolinite. It is one of the most common minerals. Kaolinite clay occurs in abundance in soils that have formed from the chemical weathering of rocks in hot, moist climates—for example in tropical rainforest areas.
Comparing soils along a gradient towards progressively cooler or drier climates, the proportion of kaolinite decreases, while the proportion of other clay minerals.
China clay is characterized by its fine particle size, high brightness and rheology. We develop fine and ultra fine grades of Hydrous Kaolin from our best reserves, for various industries including Paint, Paper, Printing Inks, Paper board, Rubber etc. China clay is a natural mineral found in partly decompo-sed granite, an igneous feldsparic rock. Chemically, kaolin is a hydrated aluminium silicate containing Al2O3.2SiO2.2H2O. Kaolin was first discovered in the mountainous province of Kiangsi, China in A.D. 500. The word kaolin derives from the Chinese character kaolin which means high ridge. It was first used by the Chinese to make high quality porcelain.
