Abstract

The co-effects of Al(2)O(3)-SiO(2) filler to an extent of 25 wt.% on thermal (softening point and coefficient of thermal expansion) and dielectric constant of lead free BaO-ZnO-B(2)O(3)-SiO(2)-Li(2)O-Na(2)O (BZBSLN) glasses have been explored with a view to use as barrier ribs of plasma display panels (PDPs). The interaction of fillers with glass occurred during firing (570 degrees C) has also been investigated by XRD, SEM micrograph and FTIR spectroscopy analyses. The fillers have been found to be partially dissolved in the glass at the firing temperature leaving some unreacted residual filler which result in ceramic-glass microcomposites. All the properties are found to follow the same experimental and theoretical trends, and regulate by the covalent character as well as the optical basicity of microcomposites. Addition of combined filler found to be yielded the required properties and meeting the criteria for barrier rib application.
