A type of artificial abrasive. 3 oxidation 2 aluminium Al2O3) content over 99%， and the composition such as containing a small amount of ferric oxide， silicon oxide， white. Size according to the international standard and national standard production， according to user requirements granularity processing. General grain sizes of the F4 ~ F220， its chemical composition depending on the size of the particle size. The outstanding characteristic is crystal size small impact resistance， if use the broken mill processing， particles are spherical particles， the surface dry clean， easy to bond. Chinese white corundum foreign names white fused product application range of mechanical engineering， abrasives， Type abrasive， sand， sand， sand F， WA sand material quality， and the amount of alumina powder containing 99% hard degree of Morse true density > 10.0 3.90 g/cm3 don~t name white aluminium oxide product introduction: white corundum industrial alumina powder as raw material， white corundum， white corundum size difference between pictures size difference between the 6) regularly over 2000 degrees in the arc after cooling in high temperature melting， after smashing plastic， magnetic separation to iron， screen is divided into a variety of particle size， dense texture， high hardness， The granule forms a sharp Angle shape， is suitable for making ceramic porcelain， resin solidification grinding， polishing， sandblasting， precision casting 《precision casting special corundum， etc.)， can also be used for making advanced refractory materials， the code name "WA" is consistent with international standard and national standard， most of them are for export， and some of them are supplied to domestic users.
