On annealing in chlorine trifluoride gas (ClF 3 ), the Iow- T c phase YBa 2 Cu 3 O x ( x ~ 6.6, T c ~ 60 K) is readily converted into a high- T c phase exhibiting 90 K superconductivity. YBa 2 Cu 3 O 6.60 ( T onset = 63 K) began to react with ClF 3 a

The reaction between cerium dioxide and fluorine gas has been studied by means of thermogravimetric, X-ray and magnetic measurements. CeO 2 reacts with F 2 gas from 130 °C and converts into CeF 3 with a characteristic weight decrease above 270 °C.
