PREPARATION AND PROPERTIES OF RAPIDLY QUENCHED GLASSES IN THE V2O5-PBO SYSTEM

Rapidly quenched glassy films in the V2O5-PbO system were prepared using a twin-roller type apparatus. The glass formation region was 0-60 mol % PbO. The first crystallization temperature increased from 210-degrees-C for the V2O5, glass to 292-degrees-C for the glass of 60 mol % PbO. The metastable unknown phase was first crystallized in the glasses around 50 mol % PbO. Infrared absorption spectra of the glasses were measured. Electrical conductivity of the glasses decreased with increasing of PbO content. The electrical behaviour of the glasses is discussed based on the glass structure estimated from the infrared spectral data.
