More Information
Summary:The invention discloses a microwave ceramic dielectric material and a preparation method thereof. The microwave ceramic dielectric material comprises the following raw materials in percentage by mass: 60-80% of Li < 1.19 > Ta < 0.81 > Ti < 0.19 > O < 3 >, 25-20% of TiO < 5 >, 5-20% of Ta2O < 5 >, 5-20% of Mn2O < 5 > and 5-20% of glass powder. The glass powder is prepared from the following raw materials in percentage by mass: 25 to 40 percent of CaF, 5 to 30 percent of P2O5, 5 to 30 percent of CaCO and 5 to 40 percent of AlF. The ceramic dielectric material is low in sintering temperature, high in dielectric constant, low in dielectric loss and high in temperature stability. 本发明公开了一种微波陶瓷介质材料及其制备方法，该材料包括如下质量百分比的原料：Li1.19Ta0.81Ti0.19O360-80％、TiO25-20％、Ta2O55-20％、Mn2O35-20％、和玻璃粉5-20％。所述玻璃粉包括如下质量百分比的原料：CaF25-40％、P2O55-30％、CaCO35-30％和AlF35-40％。该陶瓷介质材料烧结温度低、介电常数高、介电损耗低，和温度稳定性高。
