ABSTRACT:
Disclosed are pH responsive glass compositions which contain specified proportions of LiO.sub.2, SiO.sub.2, La.sub.2 O.sub.3, and Ta.sub.2 O.sub.5. In some embodiments, the glasses also contain a small proportion of Cs.sub.2 O. The glasses have very low electrical resistivity, are stable against devitrification, and are readily melted and formed into shapes which are suitable for glass electrodes.
