Summary: | The invention discloses a method for quantitatively controlling the B-position antiposition defect concentration of Sr2FeMoO6 ceramic. The method comprises the following steps of: carrying out ball milling, preburning and ball milling in sequence on the mixture of SrCO3, Fe2O3 and MoO3 powder, tabletting the uniformly mixed powder mixture to prepare a series of Sr2FeMoO6 ceramic with different B-position antiposition defect concentrations under the 5%H2/95%Ar gas mixture at the flow of 65ml/min, the sintering temperature of 1473K by regulating the sintering time to (16-4h). The equipment and preparation process required in the method are simple and easy. |
