Flash calcined alumina

WebFused aluminas are used in special refractories for the glass industry. Fused alumina is calcined alumina that is melted in electric-arc furnaces, cooled, crushed, and recast into desired shapes. In another application, industrial processes requiring hot gases use a unique heat-transfer device called a pebble heater. WebMay 1, 1999 · Alumina samples were all calcined at 600°C except alkoxide (500) and alkoxide (700) which were calcined at 500 and 700°C, respectively. The XPS results showed that more extensive dehydrogenation occurred on the surface of the sample calcined at 600°C than for that calcined at 500°C.
