Stable ceramic dielectric material and preparation method thereof
The invention discloses a stable ceramic dielectric material and a preparation method thereof. The stable ceramic dielectric material is prepared from the following raw materials in percentage by mass: 5 to 20 percent of glass powder and 80 to 95 percent of Ba (Zr < 0.15 > Ti < 0.85 >) O < 3 > to 0.3 percent CeO < 2 > to 0.1 percent MgO. The glass powder is prepared from the following raw materials in percentage by mass: 35 to 40 percent of Li2CO3, 5 to 30 percent of K2O, 35 to 30 percent of Sb2O, 35 to 30 percent of MgCO3 and 25 to 30 percent of SiO2. According to the invention, a Ba (Zr0. 15Ti0. 85) O3-0. 3CeO2-0. 1MgO system is selected, and a preparation method of a melting infiltration method is adopted, so that the sintering temperature is lower than 1000 DEG C, the system structure is stable, phase transformation is not easy to occur, and the purposes of stability and excellent performance are achieved. The ceramic dielectric material is high in temperature stability, low in sintering temperature, high in dielectric constant and low in dielectric loss.
本发明公开了一种稳定型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：玻璃粉5‑20％、Ba(Zr0.15Ti0.85)O3‑0.3CeO2‑0.1MgO 80‑95％。所述玻璃粉包括如下质量百分比的原料：Li2CO35‑40％、K2O 5‑30％、Sb2O35‑30％、MgCO35‑30％和SiO25‑30％。本发明选择Ba(Zr0.15Ti0.85)O3‑0.3CeO2‑0.1MgO系统，采取熔融渗入法的制备方法，使其烧结温度低于1000℃而且系统结构稳定，不易发生相转变，从而达到稳定型且性能优良的目的。该陶瓷介质材料温度稳定性高、烧结温度低、介电常数高，和介电损耗低。
