摘要： A ceramic powder having a perovskite structure is manufactured by synthesizing a ceramic powder by a dry synthesis process and then heat-treating the synthesized ceramic powder in a solution. The dry synthesis method includes a solid phase synthesis method, an oxalate method, a citric acid method and a gas phase synthesis method.
