用濕式化學法，以 TEOS, H3BO3, LiNO3, CaNO3．4H2O作為前驅鹽、乙二醇及檸檬酸作為螯合劑，製備Li2O-CaO-B2O3-SiO2 (LCBS)玻璃，並且利用調整檸檬酸劑量及改變溶劑種類，探討製程參數，對LCBS玻璃結構的影響。本研究使用XRD確認LCBS玻璃成分的均勻性以及結晶行為，並以FTIR及Raman光譜分析玻璃分子結構，使用DTA分析玻璃之熱性質。為確認LCBS玻璃對於鈦酸鋇陶瓷體的助燒結性質，並將LCBS玻璃加入鈦酸鋇中製成陶瓷體，以DIL確認熱收縮溫度區間，以1050-1200℃分別進行鈦酸鋇中陶瓷體燒結並分析其相對密度變化趨勢，以及介電性質表現。
過調整LCBS玻璃中之CaO/Li2O比，比較玻璃結構中[BO4]及橋氧鍵結比例以及其對於玻璃熔融溫度的影響。同時藉由XRD結構精算，分析Ca離子與Li離子對於鈦酸鋇晶格參數以及其對結構摻雜劑的擴散行為的影響。研究結果顯示，Li2O-B2O3-SiO2 (LBS)具有較佳的助燒效果與高介電常數表現，但絕緣電阻率卻相對較低；而使用CaO-B2O3-SiO2 (CBS)作為玻璃助燒結劑，雖可有效提升鈦酸鋇的絕緣電阻率，但助燒效果與介電常數則相對較低。而Li2O-CaO-B2O3-SiO2 (LCBS) 則可透過混合改性劑效應，有效在助燒效果與介電性質間取得平衡。本研究透過調整Li2O/CaO比，控制玻璃結構、晶格參數、氧空缺占比及摻雜劑的擴散速率，使用X=0.5 (0.125Li2O-0.125CaO-0.125B2O3-0.625SiO2) 作為助燒結劑，可於1200℃獲得緻密鈦酸鋇陶瓷體，並保有高介電常數、高絕緣電阻率以及低介電損耗的優異介電表現。

Li2O-CaO-B2O3-SiO2 (LCBS) glass was prepared using a wet chemical method with TEOS, H3BO3, LiNO3, and Ca(NO3)2·4H2O as precursor salts, and ethylene glycol and citric acid as chelating agents. The effects of adjusting the CaO/Li2O ratio in LCBS glass on the melting temperature were compared. Additionally, XRD structure refinement was used to analyze the effects of Ca and Li ions on the lattice parameters of barium titanate and the diffusion behavior of structural dopants. The results showed that Li2O-B2O3-SiO2 (LBS) exhibited better sintering aid effects and higher dielectric constants, but relatively lower insulation resistivity. While using CaO-B2O3-SiO2 (CBS) as a glass sintering aid effectively improved the insulation resistance of barium titanate, its sintering aid effect and dielectric constant were relatively lower. Li2O-CaO-B2O3-SiO2 (LCBS) effectively achieved a balance between sintering aid effects and dielectric properties through the mixed modifier effect. By adjusting the CaO/Li2O ratio, this study controlled the glass structure, lattice parameters, oxygen vacancy proportion, and diffusion rate of dopants. Using X=0.5 (0.125Li2O-0.125CaO-0.125B2O3-0.625SiO2) as a sintering aid, dense barium titanate ceramic bodies were obtained at 1200℃, maintaining excellent dielectric performance with high dielectric constants, high insulation resistivity, and low dielectric loss.
