| Abstract: | The phase diagram of the system La2(SO4)3Ag2SO4 was studied by DTA, XRD, SEM, and optical methods. One double salt is formed at 67 mole% La2(SO4)3 and this melts incongruently at 876±6°C. A eutectic is formed at 8 mole% La2(SO4)3 and at a temperature of 618±3°C. Suppression of decomposition was effected by the sealed tube method, but some reference is made to experiments conducted with a flowing atmosphere of SO3, SO2 and O2. |
