摘　　要：High specific surface of(α/γ)-Al_(2)O_(3)powder is essential for its applications in adsorbents,catalysts or ceramic raw materials.However,the phase transformation from precursor to oxide powder inevitably experiences the hightemperature calcination process which coarsens or agglomerates the particles,and then loses the high dispersity and activity.

关 键 词：materials ADSORBENT CALCINATION
