Low Sodium white fused alumina Description:http://www.whitecorundum.com
Low sodium white fused alumina means white corundum with Na2O＜0.2%. The Na2O content will affect hardness, temperature compressive strength and bending resistance strength,etc. With special smelting process, HAIXU Abrasive present Na2O within 0.2% and Na2O within 0.1% WFA grain and powder which are sutiable for high-level refractory and abrasive tools.
