Alumina Recovery from Kaolin with Mineral Impurities司鹏,乔秀臣School of Resource and Environmental Engineering, East China University of Science and Technology摘 要:The alumina recovery from low grade kaolin (K-JS) treated through thermal and mechanical methods was investigated. High grade kaolin (K-SX) was used as comparison. The optimum calcination......
RESEARCH ON MICROWAVE SINTERING ALUMINA CERAMICS周建摘 要:<正>This paper introduces the characteristic of microwave sintering,introduces and analyses the process of microwave sintering of the alumina ceramics, moreover, compared with the experiments of conventional sintering method. Based on the researcb, some results are obtained, and experimental......
FILTER PRESSING BEHAVIOUR OF ALUMINA DISPERSIONS曾人杰摘 要:<正>Studies of pressure-volume curves haveshown that the filter pressing behaviours depend on pHvalaes of the alumina dispersion. Densimetry andporosimetry of the filter cakes have revealed that higherdensity,smaller mode pore size and lower specific volumeof total pores can be achieved......
