White aluminum oxide powder for Polishing & grinding, a kind of high-grade refractory material, 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 alpha-Al2O3.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.

1. Not affecting the color of the processing cases;
2. Sandblasting in the non-iron process;
3. High speed processing and quality;
4. Containing a very low amount of iron oxide, suitable for non-ferrous blasting operations;
Aluminum oxide has become the most popular polish for rock tumbling and most lapidary activities. Why? Two reasons:
1) aluminum oxide does a fantastic job at polishing agate, jasper, quartz, petrified wood and most of the other materials that are polished in a rock tumbler; and,
2) aluminum oxide polishes are inexpensive - they cost less than half as much as cerium and tin oxide - the other all-time favorite polishes.
Aluminum oxide has a chemical composition of Al2O3 - the same as corundum (the mineral of ruby and sapphire). It also has a Mohs hardness of 9.
