Product Name: White Aluminum Oxide for Making Abrasives Model NO.: F600 Quality: First Class Grade Standard: Industrial Grade Classification: Aluminium Oxide CAS No.: 1344-28-1 Purity: 99.5% Melting Point: 2303k Trademark: Tianchang Transport Package: 50kg/PE Bag, 25mts/FCL Without Pallet Specification: ISO 9001 SGS MSDS COA Origin: China HS Code: 2818200000 Product Description Name: Alumium oxideMF: Al2O3Purity: 99.5% or 96%Surface: White PowderMelting Point: 2303KBoiling Point: 3250KWhite fused alumina is mainly used for grinding high carbon steel, high-speed steel and chilled steel. It can also be used as lapping and polishing medium, precision founding sand and coating materials, catalyst carrier, special ceramics and super refractory materials.1. High Purity Aluminum OxideM Oxide/Aluminium Oxide/ Alumina OxidAluminum 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.2. 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.
