Calcined alumina oxide powder Alumina, also known as activated alumina is manufactured from aluminium hydroxide by dehydroxylating it in a way that produces a highly porous material; this material can have a surface area significantly over 200 square meters/g. The compound is used as a (to keep things dry by absorbing water from the air) and as a of , and in . It is made of (alumina; Al2O3), the same chemical substance as and (but without the impurities that give those gems their color). It has a very high surface-area-to-weight ratio. That means it has a lot of very small pores, almost like tunnels, that run throughout it The appearance is white crystal powder with uniform particle size, stable chemical property, good crystal phase stability, difficult to dissolve in acid and alkali, and has good sintering activity. Aluminum oxide can be used as raw material for preparing high purity aluminum oxide powder. Aluminum oxide can be used in long afterglow phosphors, three color phosphor, abrasive materials, transparent ceramic lamp, high-pressure sodium lamp, catalyst carrier, EP-ROM window, crystal, ruby, sapphire crystal, electronic ceramics. It is widely used in electronics, chemicals, petroleum, refractories, ceramics, glass, plastics, textiles, building materials, abrasives, paper and medicine, and many other fields.

Al2O3 86-80% available in different grades as per requirement
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

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

Calcined bauxite is produced by sintering/calcining with natural bauxite ore of low iron, low alkali at temperatures of 1600 - 1800 degree Celsius in the rotary kiln or round kiln through pre-heationg, calcination, cooling and other processes. During Calcining, it can be removed impurities and improving the content of alumina. Refractory grade bauxite has high refractoriness, good mechanical strength and moderate slag resistance. Therefore calcined bauxite is one of the most important raw materials for the production of shaped and unshaped refractories for the steel industry, foundries, glass and cement plants.
