Abstract. The synthesis of beta-alumina powder from kaolin-derived aluminium sulphate solution is described. A homogeneous mixture of Al 2 (SO 4) 3 ·18H 2 O and Na 2 SO 4 ·10H 2 O was precipitated by dropping the mixed solution of the kaolin-derived aluminium sulphate and sodium hydroxide into ethanol with agitation by stirring. The preparation conditions - mixing mole ratio of Na 2 O/Al 2 O ...
