PREPARATION OF FINE α-AL₂O₃ BY THERMAL DECOMPOSITION OF HYDRAZINE-CONTAINING ALUMINUM SALT

Dept of Chemistry TongJi University Shanghai 200029

Received Date: 26 March 1990

A new method for preparing fine α-Al₂O₃ by thermal decomposition from hydrazine-containing aluminum salt was described.The process of the thermal decomposition of the hydrazine-containing aluminum salt was investigated by thermal analysis (TG and DTA) and the thermally decomposed products were studied by S.E.M and X-ray diffraction.The result indicated the particles of α-Al₂O₃ obtained in this way at 12500℃ were < 1μm in size.
