Synthèse basse température du gallate de zinc

st Brazilian Congress on Thermal Analysis and Calorimetry (I CBRATEC); Minas Gerais, Braz; 29 March 1998 through 2 April 1998International audienceThe dependence of the firing conditions on the crystal structure formation of ZnGa2 O4 has been investigated. The effects of temperature and atmosphere were examined and gave evidence of the instability of the zinc gallate under a reducing atmosphere at temperatures above 600°C. A new preparation route has allowed to synthesize ZnGa2 O4 at low-temperature, right from 300°C, avoiding the decomposition of the matrix during the annealing
