D50 value of white aluminum oxide micropowder
White aluminum oxide,also called white corundum,white fused aluminum oxide,white corundum etc,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 producing and exporting abrasives for more than 20 years.including white aluminum oxide,brown aluminum oxide and silicon carbide.
For them,we both produce macrogrit and micropowder.
About PSD,for grit,no matter produce under which standard,the PSD is almost the same,but powder has big difference.
Today,just take white aluminum oxide micropowder for example to show the D50 value of FEPA,JIS,W,M standard as follows:
