The phase diagram AgI-PbI 2

The phase diagram AgI-PbI 2 was investigated by X-ray and difference thermoanalytical methods. Two high-temperature compounds, one based on Ag 3PbI 5 the other on AgPb 4I 9, were observed. The temperature of transformation of PbI 2 into the high-temperature 12R-PbI 2 modification is decreased by the addition of AgI.

MUTUAL EFFECT ON PHASE TRANSITION TEMPERATURES OF TWO PHASES IN AgI(α-Fe2O3) COMPOSITION ELECTROLYTES

DC and ac conductivities of AgI(α-Fe2O3) composite electrolytes have been measured. It is found that the Morin transition temperature of α-Fe2O3 is dereased by the addition of AgI. The results of M?ssbauer spectra and susceptibility are qualitatively coincide with electrical measurement. Phase transition temperature of AgI from α to βphase is also significantly lowered by the existance of α-Fe2O3. The experiments have been shown that phase transition temperature of the two phases in composite electrolyte were influenced each other.
