WebbThe technical pure alumina is classified as smelter grade alumina (SGA) and contains at most 0.01–0.02% SiO 2, 0.01–0.03% Fe 2 O 3, and 0.3–0.6% NaO 2 as impurities. Alumina has to be calcined above 1250 °C to obtain complete conversion to the alpha crystalline state of alumina (α-Al 2 O 3) in order to make chemically inert, ceramic ... Webb1 maj 1999 · The only hydrated oxide known to convert directly to alpha alumina is diaspore (β-Al 2 O 3 ·H 2 O) which forms alpha alumina at temperatures as low as 500°C. The direct topotactic conversion of diaspore into alpha alumina is due to the structural similarity of the phases, both having a hexagonally close packed anion sublattices.
