P. Znasik et M. Jamnicky, PROPERTIES OF MIXED-HALIDE METAPHOSPHATE GLASSES IN SYSTEMS OF CUI-CUX-CU2O-P2O5 (X=BR, CL), Solid state ionics, 92(1-2), 1996, pp. 145-150
Cuprous ion conductive glasses were prepared in the systems (40 - x)Cu
I-xCuBr-30Cu(2)O-30P(2)O(5) and (40 - x)CuI-xCuCl-30Cu(2)O-30P(2)O(5).
Glass-formation was observed in the complete range of substitution of
CuBr or CuCl for CuI. The glass transition temperatures of prepared g
lasses ranged from 355 K up to 407 K. Infrared studies confirmed that
the glasses contain mainly metaphosphate chain groups. The conductivit
y of the glasses at room temperature is of the order of 10(-4) S cm(-1
) to 10(-3) S cm(-1) and shows a positive deviation from the additivit
y rule for both systems, with a maximum deviation for the molar ratio
X/(X + I) = 0.750.
