Abstract

Glasses in the ZnO-B2O3-MO3(M = W, Mo) ternary were examined as potential replacements to PbO-B2O3-SiO2-ZnO glass frits with the low firing temperature (500–600C) for the dielectric layer of a plasma display panels (PDPs). Glasses were melted in air at 950–1150C in a narrow region of the ternary using standard reagent grade materials. The glasses were evaluated for glass transition temperature (T g ), softening temperature (T d ), the coefficient of thermal expansion (CTE), dielectric constant (ε r ), and optical property. The glass transition temperature of the glasses varied between 470 and 560C. The coefficient of thermal expansion and the dielectric constant of the glasses were in the range of 5–8 × 10− 6/C and 8–10, respectively. The addition of MO3to ZnO-B2O3binary could induce the expansion of glass forming region, the reduction of T g and the increase in the CTE and the dielectric constant of the glasses. Also, the effect of the addition of MO3to ZnO-B2O3binary on the transmittance in the visible-light region (350–700 nm) was investigated.
