| 摘 要： | 本实验研究了(1-x)(Mg0.7Zn0.3)TiO3-x(Ca0.61La0.26)TiO3(MZT-CLT)系陶瓷的微观结构和微波介电性能,通过(Ca0.61La0.26)TiO3来协调(Mg0.7Zn0.3)TiO3陶瓷的谐振频率温度系数.MZT-CLT陶瓷的主晶相为(Mg0.7Zn0.3)TiO3,第二相为Ca0.61La0.26TiO3和(Mg0.7Zn0.3)Ti2O5.烧结温度和陶瓷组成对微波介电性能影响显著,当烧结温度为1275℃时,可以获得良好的致密度,当烧结温度超过1300℃时,Zn的蒸发导致陶瓷致密度和介电性能下降.随着(Ca0.61La0.26)TiO3含量的增大,材料的介电常数增大,品质因数减小.当x=0.13,烧结温度为1275℃保温4h,(MZT-CLT)陶瓷具有优良微波介电性能,εr=26,Q.f=86000 GHz,τf=-6×10-6/℃.

| Abstract: | The microstructures and the microwave dielectric properties of the(1-x)(Mg0.7Zn0.3)TiO3-xCa0.61La0.26TiO3(MZT-CLT) ceramic system were investigated.The objective of the present work is to compensate for the negative temperature coefficient of resonant frequency of(Mg0.7Zn0.3)TiO3 by the addition of(Ca0.61La0.26)TiO3.MZT-CLT ce-ramics exhibited mixed phases of(Mg0.7Zn0.3)TiO3 as the main phase associated with minor phases of Ca0.61La0.26TiO3 and(Mg0.7Zn0.3)Ti2O5.The microwave dielectric properties are strong... |
