Abstract :
The glass-forming region and some basic physicochemical parameters (temperatures of phase transformations, density and microhardness) of the GeSe3-FeSe2-Ag2Se system have been determined. Membranes of the (GeSe3)85/(FeSe2 )10(Ag2Se), (GeSe3)81(FeSe2)14(Ag2 Se)5 and (GeSe3)76(FeSe2 )9(Ag2Se)15 compositions for Fe(III) ion-selective electrodes have been studied. They have been characterized by the linear range and slope of electrode function, limits of detection and pH-working interval
