　　The LSCOp and LSCOw conductive ceramic powder were synthesized by sol-gel method.Ag-LSCOp and Ag-LSCOw electrical contact composites were fabricated by high-energy ball milling and sintering process with LSCO conductive ceramics as the second reinforcement phase.The results showed that LSCOp was obtained at pH=9.5 and sintering temperature of 700℃ for 8 h when using single citric acid as gelling agent, but LSCOw was obtained with citric acid and EDTA used as complex gelling agents.And when using LSCOw conductive ceramics as the second reinforcement phase, Ag-LSCOw electrical contacts showed lower resistivity than that of Ag-LSCOp.
