在本實驗中，使用傳統的球磨法來混合製作不同的陶瓷體，以摻雜釤(Sm)與錳(Mn)的PbTiO3即(Pb0.85Sm0.1)(Ti0.98Mn0.02)O3 (PT)為主體成份，並使用Ba(Cu0.5W0.5)O3 (BCW)、BiFeO3 (BF)、與SiO2等不同的摻雜添加物來幫助陶瓷體低溫燒結的達成。
　　本實驗使用X-ray diffraction (XRD)以及scanning electron microscope (SEM)來對不同陶瓷體的成份特性與微結構做分析，並探討其不同份量摻雜對陶瓷體燒結溫度與電特性的影響。由實驗結果可看出，本實驗成功地驗證了Ba(Cu0.5W0.5)O3 (BCW)、BiFeO3 (BF)、與SiO2等不同的摻雜添加物確實有降低PT陶瓷體燒結溫度的作用(由1200℃降至1100℃)，並在降低燒結溫度的同時仍保有良好的壓電與介電特性。
　　本實驗中亦成功地將不同成份的陶瓷體製作成表面聲波濾波器，並量測出波速(phase velocity)、頻率溫度係數(TCF)等特性參數。

　　Samarium (Sm) modified lead titanate (PbTiO3) ceramics with a composition of (Pb0.85Sm0.1)(Ti0.98Mn0.02)O3 (PT) piezoceramics doped with Ba(Cu0.5W0.5)O3 (BCW), BiFeO3 (BF), and SiO2 were prepared by conventional mixed-oxide method.
　　Microstructural and compositional analyses of these PbTiO3-based ceramics have been carried out using X-ray diffraction (XRD) and scanning electron microscope (SEM). The effects of BCW, BF, and SiO2 additives on sintering temperature and piezoelectric properties of these ceramics have been investigated. We have successfully showed that additives like BCW, BF, and SiO2 were helpful in lowering PT’s sintering temperature from 1200℃ to 1100℃ and still keep good piezoelectric and dielectric properties.
　　Surface acoustic wave (SAW) filters were also fabricated and properties, including phase velocity and temperature coefficient of frequency (TCF), were measured.
