D50 value of white fused alumina powder FEPA,JIS,W,M standard

D50 value of white fused alumina powder FEPA,JIS,W,M standard

White fused alumina,also called white corundum,white fused aluminum oxide,white aluminum oxide 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 fused alumina,brown fused alumina and silicon carbide.

For them,we both produce grit and powder.

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 fused alumina for example to show the D50 value of FEPA,JIS,W,M standard of white fused alumina powder as follows:
