Medium microwave dielectric ceramic powder and preparation method thereof
The invention discloses medium microwave dielectric ceramic powder and a preparation method thereof. The composite material comprises the following components in percentage by weight: 30%-35% of magnesium oxide, 55%-65% of titanium dioxide, 1.4%-2% of lanthanum trioxide, 3%-5% of calcium carbonate, 0.5%-0.7% of zirconium oxide, 0.3%-0.6% of bismuth oxide and 0.4%-0.7% of manganese dioxide. The preparation method comprises the following steps: ball-milling mixing, drying, granulation, glue discharging, sintering and the like. Compared with the prior art, the medium microwave dielectric ceramicpowder has the characteristics of low sintering temperature, low dielectric constant, high quality factor Q, low dielectric loss, excellent temperature stability and the like, ceramic sintering densification is promoted, ceramic hardness and relative density are improved, and the preparation method is simple.
本发明公开了一种中介微波介质陶瓷粉料及其制备方法，包括如下重量百分数的组分：氧化镁30～35％、二氧化钛55～65％、三氧化二镧1.4～2％、碳酸钙3～5％、氧化锆0.5～0.7％、氧化铋0.3～0.6％、二氧化锰0.4～0.7％；其制备方法包括球磨混料、干燥、造粒、排胶与烧结等步骤。与现有技术相比，本发明的中介微波介质陶瓷粉料具有烧结温度低、介电常数低、品质因数Q较高、介质损耗小、温度稳定性优异等特点，促进陶瓷烧结致密化，提高陶瓷硬度和相对密度，制备方法简单。
