Detailed Description

Product Introduction White fused alumina was made from the high quality alumina by melting above 2000°C in the electric arc furnace and cooling. It is white with the main crystal phase alphaAl2O3. White fused alumina produced intitling electric arc furnace has the adwantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved. Model&Application White fused alumina in complete model of 8-5mm,5-3mm,3-1mm,1-0mm etc. 20mm MAX . Customized size is accepted with pleasure Suitable for fire-proof materials and other high temperature material and usually used in smelting factory,industrial furnace, etc. Chemical and physical parameters white fused alumina's chemical analysis Application specification major chemical content % AL2O3 Na2O SiO2 K2O Fe2O3 abrasive F 12#-60# 99.5min 0.26max 0.08max 　 0.06max 60#-100# 99.5min 0.26max 0.09max 0.06max 120#-150# 99.5min 0.26max 0.10max 0.06max 180#-220# 99.5min 0.26max 0.12max 0.10max 230#-800# 99.3min 0.32max 0.15max 0.10max 1000#-1200# 99.1min 0.35max 0.18max 0.10max refractory sand 0-1mm 99.5min 0.29max 0.30max 0.02max 0.06max 1-3mm 3-5mm 5-8mm 10-20mm 0.3-1mm 0-0.3mm 1-2mm 0.5-1.5mm fine powder 100#-0 99.0min 0.40max 0.30max 0.03max 0.20max 200#-0 325#-0 Tips : F12-220 is macrogrits for bonded abrasive tools and sand blasting ; F230-1200 is microgrits for coated abrasive tools and polishing and lapping; Fine powder is produced by the ball mill with wall lines of aluminum ball or aluminum powder wfa's physical property item specification color white crystalline form trygonal system moh's hardness ≥9.0 true density（g/cm3） ≥3.95 coefficient of inear expasion 7—9 propotion ≥3.6 porosity ≤8.5 About Us Zhengzhou Haixu Abrasives Co.,Ltd,founded in 1999, specialized in White fused alumina , Brown Alumina Oxide , Silicon Carbide and other related products.
