CALCINED ALUMINA SIZES FOR QUARTZ CRYSTAL LAPPING
Calcined alumina is a kind of inorganic compound,made from aluminium hydroxide or aluminum oxide.
But for quartz crystal lapping,it is special calcined alumina,its microscopic shape is plate-shape.so we often call it platelet calcined alumina.
Zhengzhou Haixu abrasives co.,ltd.manufacturer of white fused aluminum oxide from 1999.but recent few years,more and more customers need plate shape alumina for other applications such as Quartz Crystal Lapping,Silicon wafer lapping etc,we develped the new alumina which is similiar to Fujimi PWA and Microgrit WCA.
