Abstract
The dc electrical properties and microstructure of x(FeO‐Fe2O3)‐(100 –x)P2O5 glasses were investigated up to a maximum of x= 75 mol%. Results indicate that, in general, the minimum resistivity of the glass does not occur at equal Fe2+] and Fe3+] concentrations, although for the special case where x= 55 mol% the minimum does occur at Fe2+]/Fe total = 0.5, as reported by other investigators. Evidence presented shows that the position of the minimum resistivity is a function of total iron content. The minimum shifts to glasses richer in Fe2+] at higher total iron concentrations.This publication has 20 references indexed in Scilit:
