本研究主題探討BaO-ZnO-Li2O-B2O3-SiO2(BZLBS)玻璃以及ZnO-Li2O-B2O3-SiO2(ZLBS)玻璃的添加對BaTi4O9陶瓷粉末燒結以及微波介電性質的影響。
玻璃中BaO的添加(BZLBS玻璃)小幅提高了玻璃轉換點、軟化點及熔點，此外也改善了與BaTi4O9間的潤濕行為。選用以上兩種玻璃作為BaTi4O9的助燒劑可大幅降低燒結溫度至900℃~925℃左右，其中BZLBS玻璃相對於ZLBS玻璃有較好的助燒效果，原因除了BZLBS玻璃具有較佳的潤濕性外，燒結時ZLBS玻璃與BaTi4O9反應造成大量的相變化，生成BaTi5O11新相的過程中阻礙了燒結緻密化的行為，而含有BaO的BZLBS玻璃可抑制元素Ba的擴散，阻止新相的產生，燒結緻密程度以及介電性質也因此獲得改善。
在微波介電性質方面，在925℃燒結溫度下，添加5 vol.% BZLBS玻璃於BaTi4O9中具有最佳的介電性質：介電常數(K)為33.5、品質因子(Q)為3030而Q × f0為19720 GHz。
