Product Description
Specifications
1.high temperature low Na2O active alumina powder.3.>99.5% alumina oxide.
4.Manufacture
Aluminum oxide, 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.

application:
The abrasive tools made of it are suitable for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand, coating materials, catalyst carrier, special ceramics and super refractory materials.
Performance and advantages
Pure, clear, white aluminum oxides.The most friable aluminum oxide and due to its high purity and largecrystal size, the crystals fracture comparatively swiftly, constantly exposing fresh cutting crystals to the workpiece.These materials are widely used in precision finishing of wood, leather, rubber, glass, etc. and in the grinding of heat sensitive alloys, taking advantage of its friability and cool cutting ability.
