white fused alumina for blasting abrasive 46# activated alumina price PV:2119
-
Category:Aluminum Oxide
SPEC:46#
Packaging:Bag Package/Small Bag Package
White fused aluminum/white corundum/WA, a
kind of high-grade refractories, was made from the high quality alumina by
melting above 2000 in the electric arc furnace and cooling. It is white with
the main crystal phase α-Al2O3. Its dense texture, high hardness, granular form
sharp corners.

1. High hardness, particle density, good circular single
particles.
2. The pure white color, without impurities, guarantee the
wear-resisting layer or wear-resisting paper colour and lustre and transparency.
3. The particle size distribution uniform concentration, single
particle shape, with the least amount of biggest wear-resisting effect.
4. It is ed commit suicide by hanging oneself more than two
thousand degrees high temperature melting of high quality white corundum as raw
material, made of fine, white corundum its stable chemical properties do not
interact with acid, alkali, with low thermal shrinkage.
