Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite The commercial value of kaolin is based on the minerals whiteness and its fine controllable particle size
Kaolin has a range of industrial applications grouped into three main market areas Paper ceramics and specialty minerals
With our warehouses in Port Harcourt and Lagos we are positioned to effectively supply 2000-5000tons of Kaolin monthly

Properties and Application:
Calcined Kaolin clay, The powder superfine, high whitwness, narrow size distribution, big specific surface area, high reaction activity, no hard agglomeration, high purity, good insulation, high temperature resistance, good surface brightness.
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.
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 micrometers to 10 micrometers or even larger. These crystals may take vermicular and booklike forms, and occasionally macroscopic forms approaching millimeter 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.
When kaolin is mixed with water in the range of 20 to 35 percent, it becomes plastic (i.e., it can be molded under pressure), and the shape is retained after the pressure is removed. With larger percentages of water, the kaolin forms a slurry or watery suspension.
We have kaolin ground up to 15 microns and with a concentration of aluminum oxide up to 36%.

Description: Kaolin is cream soft, fine grained and platy powder filler sourced from mineral Kaolinite. with alternating plates of silica tetrahedral and aluminum octahedral crystal structure
Use/Application:
Plastics
Paint
Rubber
Ceramics
Adhesives
Sealants
Shelf Life: Indefinite, but a maximum of 2 years is recommended.
Modern life would be impossible without minerals. They are used in the production of everything from paint to cosmetics, water treatment to sound proofing, concrete to ceramics. AMTC supplies minerals for every conceivable application.
In AMTC we are engaged in processing of Calcined Kaolin namely for porcelain industry, sanitary ceramics, ceramic tiles, refractories, iron & steel, chemistry and further applications.
Calcined Kaolin is an anhydrous aluminium silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.
Kaolinite is a clay mineral, part of the group of industrial minerals, with the chemical composition Al2Si2O5 (OH) 4.
Uses:
1- paper industry which consumption about 50 % of world kaolin production that 30% of paper is kaolin so it become soft, glassy touch, High-brightness, low abrasion water-washed, to improve brilliance, smoothness, and ink receptivity..
2- plastic industry: because it give the surface soft touch, resistance to chemicals, fixed form, and not electric transmitted, reduced cracking, warping and crazing,
3-ceramic industry: it is the essential substance in this industry, they make several tests to measure pottery coefficient, color degree after firing, shrinkage degree, viscosity degree, degree of firing, casting degree.
4- rubber industry: to increase tension strength, increase corrosion resistance, increase solidification, and also decrease the coast.
5- painting industry: use due to its chemical inert and covering pores, low coast white color, and dissolution in painting,
6- Refractories :contain flint clay to give a dense, strong product able to withstand much higher temperatures.
7- Adhesives and sealants Kaolin is used to control flow, penetration, and specific adhesion on application, and adhesive strength, tear strength, tensile strength, and elongation after cure.
8- Other Uses Kaolin clays are used in the manufacture of aluminum chemicals, 9- bricks,
10-cements,
11- cosmetics, pharmaceuticals,
12- animal feeds, fertilizers, catalysts, wallboard, printing ink, linoleum, flexible tile, pesticides,
13-Kaolinite can contain very small traces of uranium and thorium, and is therefore useful in radiological dating.
14- Kaolinite has also seen some use in organic farming, as a spray applied to crops to deter insect damage, and in the case of apples, to prevent sun scald.
15- When heated to between 650 and 900 °C kaolinite dehydroxylates to form metakaolin.
