摘　　要：利用化学共沉淀法制备了Sr1-xCaxRuO3系列样品。X射线衍射确定样品相结构为正交畸变钙钛矿结构。扫描电子显微镜观察了颗粒形貌，基本成球形，颗粒尺寸分布在150-300nm范围之间。Sr1-xCaxRuO3系列样品在居里温度以下具有铁磁性，但与文献报道不同的是Sr1-xCaxRuO3系列样品没有表现出金属导电性。Sr1-xCaxRuO3 series samples were prepared by using a chemical co-precipitation method. The distorted orthorhombieal perovskite structure was determined by XRD. The particle morphology of the samples was observed by SEM. It＇s basically spherical, particles size distribution is in the range of 150 to 300 nm. Sr1-xCaxRuO3 series samples are ferromagnetic below the Curie temperature, but in contrast to literatures, Sr1-xCaxRuO3 series samples have no metal conductivity.
