Calcined Bauxite: Calcined Bauxite is obtained by calcining (heating) superior grade Bauxite at high temperature (from 850 oC to 1600 oC). This removes moisture thereby increasing the alumina content. Compared to an alumina content of about 57 % to 58 % in raw Bauxite, Calcined Bauxite has an alumina content of 82 % to 86 %. The heating is carried out in rotary kilns. Calcination is done at different temperatures ranging from 850 oC to 1600 oC depending upon the customer’s application. We export Calcined Bauxite for various applications such as refractory bricks, abrasives, steel polishing, etc. We provide consistency in quality and availability of Calcined Bauxite at extremely competitive prices. Applications of Calcined Bauxite: Refractory Grade Calcined Bauxite (CB - I and CB - II Grade) : To make refractory grade, Bauxite is thermally treated at 1600 oC to produce Calcined Bauxite where the Alumina content is mostly above 82%. Brown Fused Alumina, Proppants and Road Surfacing : To make the above grades, Bauxite is thermally treated at 1000 oC - 1200 oC to produce Calcined Bauxite where the Alumina content is anywhere between 80-88% depending on the requirement. Minimum Order Quantity : 1 Containers

We are supplier and exporter of Calcined Alumina. Calcined alumina can be used in the polishing of different alumina products(mainly used in middle, fine polishing).It is also widely used in high-class aluminium refractory material, unshaped refractory materials, high aluminium ceramic product and advanced coating, etc, . Item Al2o3 % Na2o % Sio2 % Fe2o3 % D50 A4m 99.8 0.1 0.05 0.02 3.1 Alumina (Al2O3), the industrial Al2O3 is prepared from alumina (Al2O3, 3H2O) and hard alumina, and the Al2O3, which is high in purity, is usually prepared by chemical methods. Al2O3 has many isomorphic crystals, and there are currently more than 10 known types, mainly three types of crystal, namely gamma-al2o3, beta-al2o3, alpha-al2o3.Which structure is different, with different properties in high temperature above 1300 s almost entirely into alpha Al2O3.

We are supplier and exporter of Calcined China Clay. We are offering an extensive range of high-quality Calcined China Clay that is used for paints, rubber and soap industries. Features: Chemically inert Correctly formulated Enhanced shelf life Specifications: Type: Powder Colour: White Packaging - As per Client Applications- Paints, Rubber and Soap industries. China Clay is a clay mineral with the chemical composition AlSiO3O5(OH)3. It is layered silicate mineral. It is soft earthy, usually white in color, produced by the chemical weathering of Aluminium Silicate mineral like Feldspar. Commercial grades of China Clay are supplied and transported as dry powder form, semi dry noodle form or as slurry.

Features Of Calcined Bauxite Calcination is a process of heating, hence calcined bauxite is obtained by heating the high grade ore of the bauxite. Heating further removes the moisture content from the ore and thus results in the increase of the alumina content. Applications Abrasives Refractories Road surfacing
