The invention relates to a microwave dielectric ceramic material, a preparation method thereof and a microwave communication device, and belongs to the technical field of dielectric ceramics. A preparation method of a microwave dielectric ceramic material comprises the following steps: mixing raw materials MgO and MoO3 according to a molar ratio of 1: (1.5-2) to obtain a raw material; the preparation method comprises the following steps: mixing raw materials with a grinding medium, and sequentially carrying out primary ball milling, drying and pre-sintering treatment to obtain a ceramic sample block; and sequentially carrying out secondary ball milling, drying, compression molding and sintering treatment on the ceramic sample block to obtain the microwave dielectric ceramic material. Wherein the pre-sintering temperature ranges from 500 DEG C to 650 DEG C, and the pre-sintering time ranges from 2 h to 4 h; the sintering temperature is 650-800 DEG C, and the sintering time is 4-6 hours. The microwave dielectric ceramic material prepared by the preparation method can be sintered at low temperature, and has high quality factor and low dielectric constant.
本申请涉及一种微波介质陶瓷材料及其制备方法和微波通信器件，属于介质陶瓷技术领域。一种微波介质陶瓷材料的制备方法，包括：将原材料MgO和MoO3按照摩尔比1：(1.5‑2)混合，得到原料；将原料与研磨介质混合，依次进行第一次球磨、干燥和预烧处理，得到陶瓷样块；将陶瓷样块依次进行第二次球磨、干燥、压制成型和烧结处理，即得到微波介质陶瓷材料；其中，预烧的温度为500‑650℃，预烧的时间为2‑4h；烧结的温度为650‑800℃，烧结的时间为4‑6h。通过该制备方法制得的微波介质陶瓷材料，可以在低温下实现烧结，且同时具有高品质因数和低介电常数。
