研究了（Ｓｒ＿（０．４８）Ｐｂ＿（０．４８）Ｙ＿（０．０３）Ｃａ＿（０．０１））ＴｉＯ＿３基陶瓷的半导化行为。结果表明：ＰｂＯ适当过量有利于半导化。Ｒａｍａｎ光谱，ＡＥＳ（Ａｕｇｅｒｅｌｅｃｔｒｏｎｓｐｅｃｔｒｏｓｃｏｐｙ）分析表明，随着ＳｉＯ＿２含量的增加，氧空位浓度及Ｔｉ￣（３＋）浓度增大，ＸＲＤ分析表明，随ＳｉＯ＿２含量增大，轴比ｃ／ａ增大。
The semiconducting behavior of (Sr_ (0.48) Pb_ (0.48) Y_ (0.03) Ca_ (0.01)) TiO_3 based ceramics was investigated. The results show that proper PbO is conducive to semiconducting. Raman spectra and AES (Augerrelectronspectroscopy) analysis showed that the concentration of oxygen vacancies and Ti ~ (3 +) increased with the increase of SiO_2 content. The XRD results showed that the axial ratio c / a increased with the increase of SiO_2 content.
