FEATURES

A kind of artificial abrasive.3 oxidation 2 aluminium (Al2O3) content over 98%, and the composition such as containing a small amount of ferric oxide, silicon oxide, appera white.
white aluminium oxide a kind of high grade refractories, was made from the high quality alumina by melting above 2000 in the aluminium oxide grit electric arc furnace and cooling. It is white with the main crystal phase alphaAl2O3. The white alumina produced in titling electric arc furnace has the advantage of high bulk density and low porosity and the volume stability and thermal shock resistance can be improved.

grit size:12#-220#
Micropowder: 240#-1200#

character
1. Ceramic surface treatment
2. F12-F2000
3. Grinding/Polishing
4. White Aluminium Oxide
