[0017] Examples:
[0018] Table 1 shows four specific examples of different sintering temperatures and their microwave dielectric properties of the present invention. The preparation method is as described above, the microwave dielectric properties are evaluated by the cylindrical dielectric resonator method; the SrCuV 2 O 7 The powder is mixed with Ag powder, which accounts for 20% of the powder mass, and then sintered at 840℃ for 4 hours; X-ray diffraction phase analysis and scanning electron microscope observation both show SrCuV 2 O 7 No chemical reaction with Ag, namely SrCuV 2 O 7 It can be co-fired with Ag electrode at low temperature.
