| Summary: | 碩士 === 大同工學院 === 材料工程學系 === 85 === Abstract Effects of the ceramic filler (Pb1-xCax)TiO3 on the
properties of thePbO-B2O3 based sealing glass were investigated.
The flowability,crystallization,microstructure,and coefficient
of thermalexpansion(CTE) of the (filler + glass) composite will
be discussed. The experimental results indicate that the raw
materials and processing ofthe PbO-B2O3 glass play an important
role on the resulting properties of the(glass + filler)
composites. Pb3O4-containing PbO was used as the raw materialfor
the lead oxide.This suppressed the problem of lead reduction
during glassmelting and resulted in an excellent flowability of
the resulting glass. Increase of Ca content in the (Pb1-xCax)
TiO3 filler decreases the Curietemperature and CTE. The (glass
+ filler) sealing glasses with the optimum properties(CTE
andflowability) contain 20-30vol% of the (Pb0.75Ca0.25)TiO3
perovskite filler,which exhibits an initial particle size of
about 10-15 um.
