摘要： Substantially spherical alumina particles are obtained by a process comprising ageing substantially spherical alumina hydrogel particles obtained by the oil-drop method in an ammonium hydroxide solution wherein the concentration of ammonia changes continuously from an initial concentration in the range of from about 0.05 wt.% to about 0.5 wt.% to a final concentration in the range of from about 0.8 wt.% to about 2.5 wt.%. Alumina particles obtained by this process possess improved physical strength. Alumina particles which are obtained by calcining alumina particles aged in an ammonium hydroxide solution, wherein the concentration of ammonia increases continuously, at a temperature in the range of from 650.degree. to 800.degree. C in an atmosphere containing 30 mol.% or more of H.sub.2 O possesses a further improved thermal stability.
