About Kaolin

“MEREN” Kaolin

The primary constituent in kaolin is the mineral kaolinite, a hydrous aluminum silicate formed by the decomposition of minerals such as feldspar.

“Kaolin”

Kaolin, is nearly white in color. It is distinguished from other
industrial clays based on its fine particle size and pure coloring. Its ability to
disperse in water make it an ideal pigment. Kaolin is derived from the mineral
Kaolinite which comes from the Earth’s crust. It is an aluminum silicate
represented as Al2O3-2SiO2-2H2O.

The primary constituent in kaolin is the mineral kaolinite, a hydrous aluminum
silicate formed by the decomposition of minerals such as feldspar.

Kaolin Industrial Applications

Kaolin is used in a multiplicity of industries because of unique physical and chemical properties. Shape, particle size, color, softness, and non-abrasiveness are physical properties that are especially important. Chemical properties, such as comparatively low base exchange capacity, as well as other chemical properties of the kaolin surface, and relative insolubility, are governing in many uses.

kaolin Product Application

“MEREN” kaolin Product Application

Ceramic Industry

Kaolin is used in ceramic whiteware products, insulators, and refractories. Inwhitewares, kaolin aids accurate control of molding properties, and adds dry and fired strength, dimensional stability, and a smooth surface finish to the ware

Paper Industry

The primary use of kaolin is in the paper industry. It serves as a paper coating which improves appearance by contributing to brightness, smoothness and gloss.

Paint Industry

Kaolin is used in paint industry because it is chemically inert and insoluble in the paint system, has a high covering power, gives the paint desirable flow properties and is low in cost.

Rubber Industries

Kaolin is used as a filler in many rubber goods. It adds strength, abrasion resistance, and rigidity to both natural and synthetic rubber products. In general, most rubber products extrude more easily after kaolin filler is added.

Other Uses:

Kaolin has a variety of other uses in products including cable insulation, specialty films and fertilizers, glass fiber, white cement and refractory insulation bricks.. New uses are being discovered frequently, and ensure that the mineral will remain in demand for a long time.
