• Product Details

  Description: Zirconia fused alumina is produced by putting rich aluminum, zirconium materials and additives in electric furances, smelting with high temperature above 2000°C,cooling down with special technology, and compacting with Barmac plastic, which has the characteristics of tenacious texture, dense structure and high strength. Characteristic: ? A little less hardness than normal fused alumina ? Higher roughness than alumina without Zirconium. ? 40%ZrO2 Zirconia has better self-sharpening ability? abrasive tools like cutting disc and grinding wheel would be sharper and more durable. ? 25%ZrO2 Zirconia is more Suitable for making heavy duty grinding disc which works good for heat-resistant alloy steel, titanium alloy and austenitic stainless steel. Application? 1. Making zircon fused alumina brick and building materials. 2. Used for making bonded abrasives products,and process of grinding,sandblasting,surface treatment of metal products and other materials. 3. With good melt erosion resistance,Zirconia fused alumina has good grinding effect on steel,iron casting,heat resistant steel and other alloy materials. 4. Fused zirconia can be made for heavy duty grinding wheel,snagging,cutting disc,Fiber disc,grinding rails,high speed abrasive belts etc. 5. Used for making coated abrasives products. 6. Used for making lapping paste,polishing wax,emery cloth,sandpaper etc. Chemical composition Item ZA25 ZA40 AL2O3 68-72% 55-57% ZrO2 24-30% 35-44% TiO2 Max 1.5% Max 1.5% Fe2O3 Max 0.5% Max 0.5% SiO2 Max 1.0% Max 1.0% Typical physical properties Particle shape monoclinical tetragonal Chemical property Amphoteric Reaction with acid and alkali No Reaction with carbon Forming carbide since 1650 ?
