Abstract A process for preparing high-purity superfine alumina powder from aluminium alkoxide by hydrolysis includes such steps as reaction of aluminium with isopropanol in existance is catalyst to generate, aluminium alkoxide, hydrolysis to generate aluminium hydroxide and calcine. Its advantages include high purity (99.99-99.999%), sueperfine diameter less than 10 microns, high output rate (more than 92%) and smooth safety reaction.
