摘要（英）：

The invention discloses a Li3Ni2NbO6 microwave dielectric material and a preparation method thereof. The material as a ceramic material is prepared by a traditional solid-phase method and has a main phase Li3Ni2NbO6, which has a dielectric constant ranging from 14.1351 to 15.1342, a quality factor Q.f being 1.711*104 GHz to 1.974*104 GHz, and a temperature coefficient of resonance frequency being -15.6 ppm/DEG C to -13.9 ppm/DEG C. A production process of the microwave dielectric ceramic material is simple, equipment and materials for production are low in cost, and large-scale industrial production is facilitated. Prepared ceramic has various excellent features such as low loss and high dielectric constant, can serve as a material for microwave electronic components such as a dielectric resonator, a dielectric filter, a duplexer, a microwave dielectric antenna an a dielectric stable-frequency oscillator, and plays an important role in the fields of wireless internet, wireless mobile communication, satellite communication and wireless information techniques represented by military and civil radars.
