Preparation And Performance Research Of Fe₂O₃-V₂O₅-P₂O₅ Semi-Conducting Glass

Semi-conducting glass is suitable for making microchannel electron multipliers, conducting faceplates, printer fibers, and electro-optical devices. It's importance to research semi-conducting glass. In this paper a series of Fe₂O₃-V₂O₅-P₂O₅ glass has been prepared. Glass formation range, glass formation capability, the effect of glass electrical conductivity produced by interaction between Fe²⁺/Fe³⁺ and V⁴⁺/V⁵⁺ and concentration of V₂O₅ in glass, the relation between glass electrical conductivity and temperature, the relation among coefficient of thermal expansion, glass composition and annealing curve, the relation among chemical stability, glass composition and annealing curve had also been investigated. Results showed that Fe₂O₃ — V₂O₅ — P₂O₅ glass's optimization composition is: P₂O₅/V₂O₅ ratio is 2³, Fe₂O₃ is from 0³0 mol%, Al₂O₃ is from 0¹0 mol%, Sb₂O₃ is from 0⁵ mol%.
