摘要
Eight different kinds of aluminium oxide were obtained by thermal decomposition of isomorphous alunite compounds, namely, basic aluminium ammonium sulphate (BAAS) and basic aluminium potassium sulphate (BAPS). The thermal decomposition of the basic salts was performed in an atmosphere of air, in vacuum, in an atmosphere of hydrogen, and in an environment of carbon and water vapour. The Particle size distribution, phase composition, specific surface area (adsorption of benzene vapour), and the Na2O and K2O contents were determined in the aluminium oxide samples obtained.
