以TiO为还原剂，采用固相反应法成功地合成了SrxNbO 3（0.75 ≤x≤ 0.90）多晶样品。X射线粉末衍射分析表明，x≥0.80的样品为立方钙钛矿结构的单相。每个样品的电阻率在低于300 K的温度下表现出金属行为。对于x<0.90的样品，磁化率几乎与温度无关（泡利顺磁），而x=0.90的样品显示居里-外斯行为
Polycrystalline samples of Sr x NbO 3 (0.75≤x≤0.90) have been successfully synthesized by a solid state reaction technique using TiO as a reducing agent. Powder x-ray-diffraction analysis indicated that the samples with x≥0.80 were single phase of the cubic perovskite structure. Electrical resistivity of each sample exhibited metallic behavior at temperatures below 300 K. For the samples with x<0.90, the magnetic susceptibility was nearly temperature independent (Pauli paramagnetic), while the sample with x=0.90 showed a Curie-Weiss behavior
