CHINA CLAY

What is CHINA CLAY/ KAOLIN

Kaolin clay, commonly known as China clay, is naturally occurring clay that is mainly found in soil that has formed as a result of rock weathering.

The mineral kaolinite, a hydrous aluminum silicate produced by the breakdown of minerals like feldspar, is the main component of kaolin.
Chemically, kaolin is a hydrated aluminum silicate containing Al₂O₃. 2SiO₂. 2H₂O.
Kaolin comes from the Chinese word kaolin, which meaning “high ridge.”The term “high ridge” refers to the hill in south-eastern China where the clay was discovered and first used.

The mineral’s tiny particle size scatters light, contributing to its white appearance. Kaolin or China Clay is soft, earthy, and usually white in colour.

Uses of China Clay

Paper Manufacturing

Kaolin is mostly used in the paper industry. It acts as a paper coating that enhances the appearance of the paper by adding brightness, smoothness, and gloss. It also makes printing easier. It’s also utilized as a filler in the paper sector, which saves money and reduces the use of tree-based resources.

Ceramics

The high fusion temperature and white firing characteristics of China Clay make it particularly suitable for the manufacture of sanitary ware, tableware, wall and floor tiles and refractories.

Cosmetics

Kaolin processed is used as 100% natural ingredients for face creams, face masks and cosmetics. They are appreciated for their superior capabilities of mortifying skin, and absorbing sebum and other impurities.

Paints

China Clay is an excellent natural opacifier and a partial replacement for titanium dioxide. Kaolin has been proved time and again to stand on these parameters and acts as an ideal additive in high gloss paints. Kaolin is also used as an extender and flattening agent in paints.

Rubber & Plastic

Kaolin-grades processed at JJM are used for filling rubber to improve its mechanical strength and resistance to abrasion.

Pharma

Kaolin is used by reputed pharmaceutical manufactures for treating ailments, such as, mild-to-moderate diarrhea, severe diarrheal (dysentery), and cholera. Kaolin is also used to relieve soreness and swelling inside the mouth caused by radiation treatments. It also acts as a filler, as lubricants in manufacturing pills; disintegrates; ant caking and thickening agents; binders and diluents; emulsifiers; and carriers of biologically active molecules for improving drugs bioavailability

Soap and Detergents

Kaolin is used essentially as filler in soap and detergent production. It also gives the structure and acts as a riser, but the most important function of kaolin is to reduce cost of production.

Electrical Industry

It is used for electrical insulation, high voltage insulation compounds electrical wires.

In adhesives to modify rheology
In the production of common smoking pipes in Europe and Asia
In organic farming, as a spray applied to crops to deter insect damage, and in the case of apples, to prevent sun scald
As whitewash in traditional stone masonry homes in Nepal (the most common method is to paint the upper part with white kaolin clay and the middle with red clay; the red clay may extend to the bottom, or the bottom may be painted black)
As a filler in Edison Diamond Discs
As an indicator in radiological dating since kaolinite can contain very small traces of uranium and thorium
To soothe an upset stomach, similar to the way parrots (and later, humans) in South America originally used it (more recently, industrially-produced Kaolinite preparations were common for the treatment of diarrhea.
