Changes in ion composition in the liquid system CuCl2-KCl, investigated by thermogravimetry

Abstract

CuC12-KC1 mixtures were annealed at 603 K and thermogravimetrically analysed after cooling to room temperature. The mixtures differed in the molar ratio Cu/K and in the duration of heating at 603 K. The constitutions of the ions, the reactions between them and the mechanisms of their decomposition in the melt are proposed, as are the constitutions of the active centres in the oxyehlorination process.
