It was found that electrical conducting properties and thermal expansion properties of ceramic specimens closely depend on sintering temperature, Ca2+ substitution and morphological characteristics of La1-xCaxCrO3 powders.

• 研究结果表明，La_(1-x)Ca_xCrO_3陶瓷的电子导电性能和热膨胀性能与材料的烧成温度、Ca~(2+)含量、粉体的颗粒形态等因素紧密相关。
