Abstract
The paper presents data on phase transitions in pertechnetates. All tr ansformations are endothermic. The first value in parenthesis is the t emperature of the phase transition in K, the second is the enthalpy De lta H of the phase transition in kJ/mol: KTcO4 (753; 5.2), KReO4 (808; 0.1), Bu(4)NTcO(4) (345; 19.0), Bu(4)NReO(4) (371; 7.3), CsTcO4 (420; 0.86), Et(4)NTcO(4) (318; 5.0). Fusion temperature and enthalpy: KTcO4 (815; 28.4), Bu,NTcO4 (508; 20.9).
