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.
Calcined alumina powder we can supply any quantity..

Services: Installation services
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
