摘要：
Thermal properties of rare earths oxosalts containing acid anions formed with elements of VI group and nitrogen were systematized. The anomaly of thermal dissociation for sulphate-sulphite and selenite-selenate vapors was established. Cerium compounds are the least thermo stable in series iso-anion salts of rare earth salts. Peculiarity of thermal dissociation of oxosalts the anion of which is formed with non-metal is formation of intermediate stable compound like Ln(2)O(2)CO(3), LnONO(3) containing LnO+ crystal chemical ion. Similar oxocompounds are formed at the thermal dissociation of halogens and chalcogenides of rare earth metals in air.
