Abstract

Investigations on the System BiOCl/SeO 2 .-The quasibinary section BiOCl/SeO 2 contains only one compound, BiSeO 3 Cl, which shows two phase transitions upon heating, α→β at 400 • C and β→γ at 410 • C. The compound melts peritectically at 417 • C. As evidenced by chemical vapor transport experiments, BiSeO 3 Cl molecules exist in the gas phase. Standard thermodynamic data are determined by solution calorimetry and by using vapor pressure and chemical transport rate data. -(OPPERMANN, H.; HUONG, DAO QUOC; ZHANG, M.; SCHMIDT, P.; POPOVKIN, B.
