kaolin, also called china clay, soft white clay that is an essential ingredient in the manufacture of china and porcelain and is widely used in the making of paper, rubber, paint, and many other products. Kaolin is named after the hill in China (Kao-ling) from which it was mined for centuries. Samples of kaolin were first sent to Europe by a French Jesuit missionary around 1700 as examples of the materials used by the Chinese in the manufacture of porcelain.
In its natural state kaolin is a white, soft powder consisting principally of the mineral kaolinite, which, under the electron microscope, is seen to consist of roughly hexagonal, platy crystals ranging in size from about 0.1 micrometre to 10 micrometres or even larger.
These crystals may take vermicular and booklike forms, and occasionally macroscopic forms approaching millimetre size are found. Kaolin as found in nature usually contains varying amounts of other minerals such as muscovite, quartz, feldspar, and anatase.
In addition, crude kaolin is frequently stained yellow by iron hydroxide pigments. It is often necessary to bleach the clay chemically to remove the iron pigment and to wash it with water to remove the other minerals in order to prepare kaolin for commercial use.
Kaolin: Kaolin uses are multiple and diverse. Kaolin are used as functional filler, extender, ceramic raw material and pigment because of its whiteness and fine particle size. Kaolin also hold importance as raw material in refractory applications, concrete, rubber and fiber glass manufacturing. We, as a Kaolin Exporter welcome any size of international orders from Middle East and other countries. Applications: Paper: Kaolin used as a coating pigment and as a filler to replace fiber. It possesses desirable optical properties. Concrete: Kaolin helps to improve strength and durability of concrete. When added to concrete mix, reacts with free lime released during cement hydration to produce additional cementitious material, resulting in an improved high performance concrete. Plastics : Kaolin is widely used as filler in the plastics industry because of its inert chemical nature and its unique size, shape and structure. Agriculture : It is used as a carrier and diluent in fertilizers, pesticides and related products. It is suitable as carrier because it aides the retention of the formulations on the plant. Rubber : It is commonly used as functional filler in rubber applications. While Kaolin improves overall performance for Rubber in general, different types of white pigment play specific roles in rubber application. Paint : Kaolin used as an extender in paints. It reduces the amount of expensive pigment such as Titanium Dioxide. It assists with desirable rheological properties that help maintain proper dispersion and provide bulk to the product. Ceramic : Kaolin improves whiteness and brightness of ceramic body. Good plasticity, good shrinkage, low water absorption and casting rate are also very important properties of kaolin.
Kaolin also called as China Clay is nearly white in colour. It is distinguished from other industrial clays based on its fine particle size and pure colourings. Its ability to disperse in water makes it an ideal pigment. The primary constituent in kaolin is the mineral kaolinite, a hydrous aluminum silicate formed by the decomposition of minerals such as feldspar. Hydrous kaolin is characterized by its fine particle size, plate like or lamellar particle shape and chemical inertness.

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.
