Sell Nano Aluminum Oxide: Specifications: Model: HTAl-01, HTAl-02 Appearance: white powder Crystal: alpha, gamma The nature of the surface: hydrophilicity, lipophilicity Al2O3 content: > 99% Average size: < 80 nm Specific surface area: > 10 m2/g Nature and purpose: The product is a white loose powder, and is mainly divided into two types according to the different crystals: alpha and gamma. The crystal of HTAl-01 is Alpha, while HTAl-02 is gamma crystal. The surface of the product has been treated by different surface treatment chemicals to make it have better hydrophilic or lipophilic. Due to its small grain size, nano aluminum oxide can be used to make artificial jewel, analytical reagent, nano catalyst and carrier. It can greatly improve the luminous intensity, when used in the luminescent material. For the plasticization and reinforcement of ceramics and rubber, it is better than the ordinary aluminum oxide by several times, especially for the improvement of the co...

Our brown fused alumina is calcined on high temperature, air-washed and high volumic-density shaped, which can be fused and crystallized under high temperature from a mixture of bauxite and other raw materials. It is characterized by its high hardness, good toughness and sharp shape in size. Abrasives tools made of it are suitable for grinding metals of high-tensile strength, such as carbon steel, general-purpose alloy steel, annealed malleable iron and hard bronze, etc. It also can be used as refractory materials. Buyer�s satisfaction is our seeking best goals.

Zhengzhou Hongji Special Refractory Co., Ltd who is professional producing the brown fused alumina (artificial corundum) in China. Adopt the tilting furnace producing arts, our products owns higher density, purity, and better stable quality than other common ones. we can supply you the goods just in time based on our month producing capacity 2000Mts.So, if you feel interested in that please be free to contact me.

White aluminum oxide has white color and a little higher hardness and toughness comparing with the brown one. The grinding tools made of this material are suitable for fine grinding of high carbon steel, high-speed steel and stainless steel, Abrasive powder of finer grit size can also be used for precision casting and high-grade refractory.

Black aluminium oxide abrasive (Lower Aluminium Oxide Abrasive) is a new type abrasive material for polishing various metal works. It is electrical fused an arc furnace from aluminium oxide as raw material. Black aluminium oxide abrasive is featured with high hardness. Strong ten aclty, good self-sharpening. Better cohesiveness durability, less heat generated in grinding and giving the metal works high finish, less power weakened in grinding. It is mostly used in grinding and polishing stainless steel, metal works, optical glass, bamboo or articles. And it is also the new grinding material of producing colophony grinding wheels, slice, and emery cloth. With high toughness, BA is extremely suitable for polishing stainless steel and non-ferrous metals. Its grinding efficiency is much higher than that of brown A/O and the finishing effect is much better than many of other abrasive materials.
