11the low specific resistance glass of Ω-cm order of magnitude.
Background technology
Sheet glass (being also float glass) has a wide range of applications in the every field of national economy and people's lives.Along with scientific and technological development, sheet glass is also all the more general in the application of field of scientific study.As resistive plate chamber detector (RPC) and many gap Resistive Plate Chambers (MRPC) detector that last century, the nineties grew up all use sheet glass as main raw.The volume specific resistance (normal temperature) of conventional glass is 10
12～10
13between Ω cm, it can think a kind of semi-conductor, and its electrical conduction mechanism is the migration of the monovalent base metal ion in glass and the faint ionic conduction that produces.Adopt the particle counting rate of the MRPC that conventional float glass makes to be less than 1KHz/cm
2.Some large-scale Physical Experiment (as the heavy particle Physical Experiment in German GSI accelerator laboratory) requires MRPC can reach 20KHz/cm
2counting rate, like this, simple glass can not meet requirement.In order to improve the particle counting rate of MRPC, need to adopt the glass of low-resistivity, the body resistance of glass is low to 10
10～10
11Ω cm.Simple glass is a kind of ionic semiconductor, and our low specific resistance glass of development is a kind of electron conductive type glass.Its electrical conduction mechanism can jump over little polaron (small polaron hopping) and explain.When in glass, contain transition metal oxide time, two or more valence state metal ion coexists, so glass has semi-conductor behavior, the volume specific resistance of its result glass reduces.The present invention is based on Fe
