Sažetak
Investigations directed toward the preparation of the common IA3 phase of thallium oxide by thermal decomposition of thallium nitrate has led to the synthesis of novel and previously undescribed thallium oxide phases under controlled conditions. An unexpected material with a perovskite-like MMO3 (M=Tl3+) structure was formed. Two other thallium oxide phases that appear to be highly anion deficient were also discovered. It is argued that the perovskite phase is produced by the reaction of Tl2O3 (cubic IA3 rare-earth structure) with Tl2O formed by thermal decomposition and the oxidation of a Tl5O4Tl product of reaction. These materials show temperature-dependent insulating and conducting properties.
