However, the [gamma]S[Delta] of ball milled [alpha]-aluminas increases after grinding and varies after heat treatment, showing a maximum value for a treatment in the 300-350C temperature range. The formation of a thin amorphous hydrated alumina layer is postulated. Alpha Alumina Versal alpha alumina is derived from high temperature calcination of Versal pseudoboehmite and bayerite aluminas. Since each application for alpha alumina can require variations in density, surface area, hardness and deagglomeration characteristics, UOP can custom manufacture calcined alumina from any chosen Versal alumina ...
