摘要:通过Mg2+,Zn2+相互取代,制备出(MgxZn1-x)2SiO4系列微波介质陶瓷材料。实验结果表明:在(MgxZn1-x)2SiO4体系中,Mg2+,Zn2+相互取代降低了体系的烧结温度,随着x的增加,主晶相由具有硅锌矿结构的Zn2SiO4单一相,经历Zn2SiO4和Mg2SiO4相共存,逐渐转变成具有橄榄石结构的Mg2SiO4单一相。其中(Mg0.7Zn0.3)2SiO4样品的综合性能最佳,其烧结温度低(1 400℃),介电常数εγ=6.75,介电损耗tanσ=1.86×10-3。
The Mg2SiO4-type microwave ceramics in(MgxZn(1-x))2SiO4 system were prepared.The experimental results indicate that the sintering temperature of(MgxZn(1-x))2SiO4 system was reduced with the replacement between Mg^2+ and Zn^2+.And with the increasing of x value,the major crystalline phases were transformed from single willemite to coexisting willemite and forsterite,and finally single forsterite.Among all samples,(Mg(0.7)Zn(0.3))2SiO4 exhibited the best properties of sintering temperature(1 400 ℃),dielectric constant(εγ=6.75) and dielectric loss(tan σ=1.86×10^-3).
