ABSTRACT:
A composition for a bulk conducting glass comprising P.sub.2 O.sub.5, V.sub.2 O.sub.5, PbO, and FeO, the ratio of the molar percentage of P.sub.2 O.sub.5 to V.sub.2 O.sub.5 being in the range of about 1 to about 6, and the P.sub.2 O.sub.5 and V.sub.2 O.sub.5 being present in an aggregate amount of at least about 50 mole percent, the PbO being present in the glass in an amount in excess of 15 mole percent, and the FeO being present in amount of about 0 to about 30 mole percent. The composition may also include MnO or Sb.sub.2 O.sub.3 in an amount of up to about 2 mole percent. The composition may be formed into fibers for use in microchannel plates and other devices where bulk conductivity in glass is advantageous.
