Effect of Bi₂O₃Content on Properties of Lead Silicate Glass for Microchannel Plate

Abstract:

As a key material for microchannel plate, the lead silicate glasses doped with different content of Bi₂O₃ was prepared by melt-quenching method. The effect of Bi₂O₃ content on thermal properties, chemical stability, and resistivity before and after hydrogen reduction of the prepared glasses were studied. The results show that the coefficient of thermal expansion increases with the increasing of Bi₂O₃ content, while the transition temperature and softening temperature, the acid and alkali resistance, the volume and surface resistivity decrease gradually. Glass with 10% Bi₂O₃ and without PbO was used to prepare MCP, which has a resistance of 70MΩ and gain of 4,200 at 900V.
