Abstract

Microporous membranes of hexaaluminates (Ba- and La-Al₂O₃) showed heat resistance much higher than that of the conventional Al₂O₃ membrane. Although the Al₂O₃ membrane cracked by the heat treatment above 1000°C due to γ-α transformation. Ba- and La-Al₂O₃ membranes retained crack-free microstructure and exhibited excellent selective gas permeation after calcination up to 1000°C.
