Microwave dielectric ceramic material and preparation method thereof
The invention discloses a microwave dielectric ceramic material. The microwave dielectric ceramic material comprises the following raw materials in percentage by weight: 40%-50% of BaTiO3 powder, 42%-52% of TiO2 powder, 5%-10% of ZnO powder, 0.5%-3% of CuO powder, 0.1%-0.3% of ZrO2 powder and 0.2%-0.4% of La2O3 powder. The preparation method of the microwave dielectric ceramic material comprises the following steps: step 1, burdening and ball-milling; step 2, drying and granulating; step 3, compression molding; and step 4, sintering. The microwave dielectric ceramic material prepared by the invention is low in dielectric constant, high in quality factor and stable in resonance-frequency temperature characteristics, and can be applied to dielectric resonators, filters, oscillators in L-bandsatellite communication and mobile communication systems and to microwave components of a Beidou global positioning system.
本发明公开了一种微波介质陶瓷材料，按照重量百分比计，所述微波介质陶瓷材料的原料包括如下组分：BaTiO3粉40％～50％，TiO2粉42％～52％，ZnO粉5％～10％，CuO粉0.5％～3％，ZrO2粉0.1％～0.3％，La2O3粉0.2％～0.4％。所述微波介质陶瓷材料的制备方法，包括如下步骤：步骤一、配料及球磨，步骤二、干燥造粒，步骤三、压制成型，步骤四、烧结。本发明制备的微波介质陶瓷材料介电常数低，品质因数高，谐振频率温度特性稳定，可应用于L波段卫星通信与移动通信系统中介质谐振器、滤波器以及振荡器和北斗全球定位系统的微波元器件中。
