title: Effect of Al2O3 Nano-Filler on Properties of Alkali/Alkaline-Earth Borosilicate Glass Composite Sealants.
abstract: The effect of adding Al2O3 nano-filler (5 and 10 vol%) to two different alkali/alkaline-earth borosilicate glass sealants, particularly on the viscosity and electrical characteristics of the glass composite sealants, was investigated to improve the cyclic sealing performance. The effects of the filler and base glass composition on the viscosities, electrical conductivities, and phase transformations of the sealants were investigated. The glass viscosity was decreased by replacing 20 mol% SrO with alkali and zirconium oxide in a base alkaline-earth glass. Alumina filler increased the high-temperature electrical conductivities, as well as the viscosities, of the heat-treated glass composite sealants. The replacement of 20 mol% SrO with alkali and zirconium oxide in the base alkaline-earth glass decreased the electrical conductivity of the heat-treated glass containing Al2O3 nano-filler.
