Abstract
Direct synthesis of K-beta- and beta "-gallates by Ga2O3-K2O solid-state re action is described. The formation of K-beta- or beta "-gallates depends on the initial Ga2O3 phase. alpha-Ga2O3 leads to K-beta-gallate; beta-Ga2O3 l eads to K-beta "-gallate. K-beta "-Gallate is stable < 1200 degrees C. The high temperature stability of K-beta "-gallate can be enhanced by doping wi th aliovalent ions. (C) 2000 Elsevier Science B.V. All rights reserved.
