以硝酸钡（Ba（NO3）2）、硬脂酸（HST）、和钛酸四丁脂（Ti（OC4H9）4）为主要原料，用SAG法（硬脂酸溶胶──凝胶法）制备了钛酸钡（BaTiO3）纳米粉料，用JOBINYVON公司的U－1000喇曼光谱仪测量了不同温度下的喇曼光谱，通过与已指认过的喇曼谱进行比较，对获得的喇曼谱进行了分析。
Using barium nitrate (Ba (NO3) 2), stearic acid (HST), and tetrabutyl titanate (Ti (OC4H9) 4) as the main raw materials, SAG (stearic acid sol- The BaTiO3 nanopowder was measured by Raman spectroscopy with JOBINYVON U-1000 Raman spectroscopy. The Raman spectrum was obtained by comparison with the previously identified Raman spectrum Analysis.
