摘要：
A coating procedure using preformed indium (hydrous) oxide particles dispersed in aqueous solutions of hafnium oxychloride in the presence of sulfate ions is described. The concentration of the latter controls the thickness of the hafnium (hydrous) oxide shell produced. Above a certain concentration of Na2SO4 a mixed dispersion is obtained. On calcination at 800°C the core and the coating of the composite particles are converted to the corresponding oxides. © 1993 by Academic Press, Inc.
