Preparation method of novel proton ceramic conductor
The invention discloses a preparation method of a novel proton ceramic conductor, which comprises the following steps: 1, respectively weighing barium carbonate, strontium carbonate, tin oxide and scandium oxide according to the stoichiometric ratio of Ba0. 5Sr0. 5Sn0. 7Sc0. 3O3-delta, adding into a ball milling tank, and carrying out ball milling on a planetary ball mill for 12 hours by taking absolute ethyl alcohol as a solvent and zirconium oxide beads as a grinding body; 2, drying the mixture subjected to ball milling under an infrared lamp at the temperature of 80 DEG C to obtain uniformly mixed precursor powder, and then calcining the precursor powder to obtain Ba < 0.5 > Sr < 0.5 > Sn < 0.7 > Sc < 0.3 > O < 3-delta > powder; step 3, mixing the prepared powder with anhydrous alcohol, adding the mixture into a ball milling tank, taking zirconium oxide beads as grinding bodies, carrying out ball milling on a planetary ball mill for 12 hours, and drying the ball-milled mixture under an infrared lamp at 80 DEG C; and 4, carrying out single-axis pressing on the dried powder for 1 min under the pressure of 150 MPa to obtain a button cell, and sintering the button cell in a muffle furnace to obtain the Ba < 0.5 > Sr < 0.5 > Sn < 0.7 > Sc < 0.3 > O < 3-delta > proton ceramic material. The perovskite material has the advantages of good perovskite structure and chemical stability, high proton conductivity and low thermal expansion coefficient.
