| Description: | 1.Product Deion Zirconia Fused Alumina is produced in an electric arc furnace at temperatures in excess of 2700°C. Zirconia is very thermally stable to high temperatures (excellent thermal shock resistance), has low thermal conductivity, and is chemically inert. 2.Grit Size F grade F8, F10, F12, F14 ,F16, F20, F22, F24, F30, F36, F40, F46, F54, F60, F70, F80 ,F90, F100, F120, F150 ,F180, F220. P grade P12, P16, P20, P24, P30 ,P36, P40,P50,P60,P80,P100,P120,P150,P180,P220 3.Usage Zirconia is also not wetted by many metals and glasses and is therefore an excellent contact material in the existence of slags. Zirconia can also be combined with alumina to make a tough abrasive grain used in bonded and coated abrasives. Fused Zirconia is used in steel and glass contact refractories, investment casting as shell building material, as wear resistant coatings, thermal barrier coatings, and other applications that require high temperature, wear resistance, and frequent thermal cycling. 4.The manufacturing process 1.Electric Arc Furnace Put the rich aluminum, zirconium materials and additives in electric arc furnaces 2.Cooling Cooling down with special technology more than one week 3.Crushing The original block is working by crusher machine 4.Sizing The classification is carried out by abrasive sieve. 5.Washing Remove impurities 6.Packaging Packed as customers requirements. 4.Chemical property Name Al2O3 ZrO2 SiO2 TiO2 Fe2O3 ZA25 68%-72% 20-26% 0.4% 0.4% 0.3% ZA40 58%-60% 36-40% 0.4% 0.4% 0.3% 5.Physical property Color Grey Shape Blocky, tough and sharp Crystal Form Alpha-alumina,a-Al2O3,Al2O3-ZrO2.combined tree system True Specific Gravity 4.60g/cm3 Melting Temperature About 2000 Degrees Celsius Magnetic Material 0.030% Bulk Density(g/cm3) 2.24-2.18 g/cm3 | |
