摘要：

Hollow spherical particles of yttrium compounds were obtained by coating a polystyrene latex with yttrium basic carbonate layers and subsequently calcining at elevated temperatures in air. In order to establish the optimum conditions for the preparation of such hollow spheres, temperature and heating rate were systematically varied. The size of voids and of shells could be altered by using as the starting powder particles covered with inorganic layers of different thickness. © 1991 Academic Press, Inc. All rights reserved.
