초록

The effect of $Al_2O_3$ on the dielectric constant and the coefficient of thermal expansion of lead borosilicate glasses for the application of PDP glass paste was investigated. Measurements were made theoretically by using empirical equations on the composition of the of glasses in which the $PbO/Al_2O_3$, $B_2O_3/Al_2O_3$ and $SiO_2/Al_2O_3$ ratios were systematically varied. As a result, with increasing $PbO/Al_2O_3$ the thermal expansion coefficient and the dielectric constant noticeably increased, while the change of $B_2O_3/Al_2O_3$ and $SiO_2/Al_2O_3$ ratios did not affect those properties of the glasses.
