WHITE FUSED ALUMINA FOR LAMINATE FLOORING
White fused alumina is also called white aluminum oxide,white corunudm,white emery sand,white electrocorundum etc,it is 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.
Zhengzhou haixu abrasives co.,ltd,founded in 1999,has been manufacturing and exporting white fused alumina for more than 20years,we mainly produce the following sizes:
