Thick Film Glasses.
Abstract
The technicA1 literature was reviewed in order to characterize the thermal expansion, viscosity, surface tension and wetting behavior as functions of composition for glasses of present or potential use in thick film formulations. The applicability of the principle of additivity to all properties was investigated, and good correlations were demonstrated between thermal expansion and composition in some regions of the PbO-B2O3-SiO2-Al2O3 system. Experimental studies were conducted with a lead borosilicate glass as a function of A12O3 additions. The properties measured were: thermal expansion from room temperature to the deformation point for both annealed and unannealed samples; viscosity from the strain point to the softening point; and initial stage sintering kinetics from which the surface tension to viscosity ratio was obtained.
