Abstract

hermal decomposition behaviour of the citrates of zinc, bismuth and calcium has been investigated individually and as binary mixtures (1:1) consisting of zinc citrate as the essential component. Zinc citrate is found to decompose to zinc oxide at 400° C, bismuth citrate decomposes to α -Bi2O3 at 360° C and calcium citrate decomposes to calcium oxide at 1150° C. The barium and calcium oxides which are normally formed at a higher temperature during the individual decomposition of the citrates are obtained at lower temperatures, i.e. 1140 and 800 °C, respectively, on decomposition of their mixtures with zinc citrate. Bismuth citrate alone is found to decompose to α-Bi2O3 whereas its mixture with zinc citrate decomposes to the β-phase of bismuth oxide.
