Bulk density high, Low impurity content and so on. using: calcined kaolin and metakaolin all can be widely used in Papermaking Industry,Coating Industry, Oil and Paint Industry, Rubber Industry, Plastic Industry, PVC Industry, Ceramics, Cable Industry and so on.

Kaolinite is the mineral that is derived from the rock called â??Kaolinâ?? and from there, it gets its name. It is also commonly known as â??China Clayâ??. Kaolin is mined from the regions of Gujarat, Rajasthan, Kerala, West Bengal and Jharkhand in India The physical properties of Kaolin include high brightness, non-abrasiveness, poor conductivity of heat and electricity and it has naturally fine particles. Kaolin remains white after calcination due to its refractory properties and can be easily dispersed in water. There are several variations within Kaolin such as Hydrous Kaolin, Metakaolin and Calcined Kaolin. We offer a vast range of Kaolin-based minerals to several businesses from paper manufacturing to porcelain tableware, paints, cosmetics, packaging, rubber and pharmaceuticals to name a few. We customize our minerals according to the needs of the industry of our clients. Hydrous Kaolin has fine particles with plate-like shapes and inertness in terms of chemical reactivity, whereas, Metakaolin is created by the process of calcination of Kaolin. It is a white mineral additive which is most popularly used in cement-based products. In contrast to this, Calcined Kaolin is manufactured by heating the finest natural kaolin to high temperatures in a kiln. This calcination process changes the size and shape of the particles, enhances the whiteness and hardness of the mineral and improves its electrical conductivity. Kaolinite is a clay mineral, with the chemical composition Alâ??Siâ??Oâ??(OH)â?? Various Industrial Usages: Kaolin is a very important mineral in the ceramics industry. Itâ??s high fusion temperature and white firing characteristic makes it perfect to be used in the manufacture of sanitaryware, tableware, floors & tiles and refractories. In the construction industry, kaolin is used to enhance the mechanical properties, porosity and look of several types of cement and concrete. It is also an impeccable source of alumina source in the manufacturing of fiberglass. Kaolin is used in paper manufacturing and fiber-based packaging also. Our Kaolin mineral enhances surface functionality when it is used as fillers or coating pigments and thus further helping in reducing the manufacturing cost of the paper or the packaging. Moreover, it is extensively used in decorative paints formulations as it is a natural opacifier and it is the perfect mineral when high gloss is required. Our specialized Kaolin also can be used as multi-purpose fillers to improve the performance of adhesives, plastics and rubber. We are extremely confident in our offering of Kaolin mineral as we understand how Kaolin can optimize the performance, reduce the costs and can achieve minimum carbon footprint in our clientâ??s end products

Specifications Products : Hydrous, Water Washed, Classified Use : Industrial Use Color : White to Super White Form : Lumps, Powder, Noodles Packing Type : Plastic Bags / Jumbo Bags Packing Size : 25kgs/50kgs/ 1000kgs Kaolin is a hydrated aluminium silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. It is a white soft mineral composed primarily Kaolinite mineral having chemical composition of Al2O3.2SiO2.2H2O with minor amounts of quartz, feldspar and sheet silicate minerals (mica, illite, smectite). Hard and soft clays are characterized by its fine particle size, platy or lamellar particle shape and chemically inertness. Clays having fine particle size are described as hard clay. Phyllosilicates being a sub group of silicate minerals that has typically less than 2um in diameter. The combination of platy shape and fine particle size results in improved processibility, improved reinforcement, tensile strength, abrasion and tera strength. After mining the above mineral ore is dressed, dried, pulverized, air-floated, water washed (levitated), calcined and surface modified. As per the application the grades are selected by the end user. The processing techniques at PEEKAY MINERALS ensures consistent quality, control of top-cut and average particle size and freedom from impurities at pocket friendly costs. Application & Features: Ceramics: China Clay is an essential constituent in Ceramics. It is used by almost manufacturer worldwide in Electrical porcelain, Fine China & dinnerware, Floor and Wall Tile, Roof Tile, Pottery, Sanitary ware, Tableware and other engineering products. The properties important for the use of China Clay in Ceramics are Plastic Properties, Drying properties, Firing properties, Firing Color, Electrical properties such as conductivity, dielectric content etc. Our clay permits product to be easily deformed under stress without rupturing and retains shape produced when stress is removed. Due to low water of plasticity, it does not require intense forming pressure to withstand handling/drying and the Green Strength is better. The Firing properties are excellent to produce super white finish. The processed clay is free from grits and all metallic impurities. The particle size is very low and even which keeps drying shrinkage in desired parameters.

I am Erin from Shanxi Hengyuan Kaolin Co., Ltd., professional in calcined kaolin around 19 years. Calcined Kaolin used as an Extender & Filler for Water Based Paints, like building paints, electrophoretic coatings ect. Also highly used in coated paper, thermal paper, newspaper, ceramic, rubber ect. Hope to establish business relationship with you! Should you wanna know more about our company, pls visit

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.

Our company for very different mineral product line (kaolin, manganese dioxide, talc, sepiolite, zeolite, graphite) is producing or has supplied and are one of the leading firms in Turkey on this issue. "Kaolin" is a raw material characterized by the only mineral such as Ca and Na montmoryonite (bentonite) among the clay raw materials, in other words kaolinite mineral. In industrial use, it is included in the statistics under "kaolin" as "calcined". Raw materials in which kaolinite is enriched among kaolinitic clays are included as "kaolin" and others are included in clay raw materials, regardless of their origin. For example, although ball lock is a kaolinitic clay, enrichment as "kaolin" is both very difficult and industrially unnecessary. With its non-clay minerals, other clays (illite-smectite group) and organic matter content, ball clay is a very good kaolinitic clay raw material with high plasticity. Brightness, abrasiveness, viscosity and grain size distribution-max grain size-shape of the produced kaolins and their rheology (water + clay behavior) are very important. All these properties are determined by the formation conditions of kaolin and developed by post-production processes.
