A composite sintering agent and a method for preparing nano crystalline ceramic at low temperature using the same are provided. The composite sintering agent comprises a sintering aid and a grain growth inhibitor. The sintering aid comprises oxides of one or more metals selected from Li, Na, Ga, In, Mn, Fe, Co, Ni, Cu, Zn and Bi. The grain growth inhibitor comprises oxides of one or more metals selected from Mg, Ca, Al, Zr and Y. The nano crystalline ceramic can be obtained by adding the composite sintering agent into ceramic material and the sintering temperature is not higher than 900?.
