Microwave attenuation ceramic material, preparation method and application thereof
The invention discloses a microwave attenuation ceramic material, which comprises a matrix phase and a microwave attenuation phase. The average particle size of the microwave attenuation phase is 1-2microm; the microwave attenuation phase is uniformly distributed at grain boundaries of the matrix phase to form a grain boundary network structure. The high-power high-frequency microwave vacuum electronic device prepared from the microwave attenuation material has high thermal conductivity and good attenuation. The invention also discloses a preparation method and application of the microwave attenuation ceramic material.
本发明公开了一种微波体衰减陶瓷材料，该陶瓷材料包括基体相和微波衰减相，所述微波衰减相的平均粒径为1‑2μm；所述微波衰减相均匀地分布在所述基体相的晶粒间界，形成了晶界网络结构。该微波体衰减材料制备得到的大功率高频微波真空电子器件具有高导热率和好的衰减量。本发明还公开了该微波体衰减陶瓷材料的制备方法和应用。
