Abstract	本发明公开了一种微波介质陶瓷材料及其制备方法和电子器件，微波介质陶瓷材料由包括陶瓷主晶相和烧结助剂的原料烧结制得，所述烧结助剂为复合氟化物，所述复合氟化物选自LF、MF2、ReF3和NF4中的至少两种，其中L为碱金属元素，M为+2价金属元素，Re为稀土金属元素、Al、Ga或Bi，N为+4价金属元素。本发明使用具有低熔点的复合氟化物作为烧结助剂，能够在较低的温度下烧结制备出具有连续可调的中介电常数及低介电损耗等优良微波性能的微波介质陶瓷材料。
Other Abstract	The invention discloses a microwave dielectric ceramic material and a preparation method thereof, and an electronic device, the microwave dielectric ceramic material is prepared by sintering a raw material comprising a ceramic main crystal phase and a sintering aid, the sintering aid is a composite fluoride, the composite fluoride is selected from at least two of LF, MF2, ReF3 and NF4, L is an alkali metal element, M is a divalent metal element, Re is a rare earth metal element, Al, Ga or Bi, and N are valence metal elements. According to the invention, the composite fluoride with a low melting point is used as a sintering aid, and the microwave dielectric ceramic material with excellent microwave properties such as continuously adjustable medium dielectric constant, low dielectric loss and the like can be prepared by sintering at a lower temperature.
