| 摘 要： | 以Li2CO3、B2O3和V2O53种常见的低熔点氧化物为烧结助剂,用传统固相法制备了Li2CO3-B2O3-V2O5掺杂的ZnO-TiO2微波介质陶瓷,并利用XRD、SEM等研究了ZnO-TiO2陶瓷的烧结行为、物相组成、显微结构特征及微波介电性能等。结果表明,当掺入3%(质量分数)Li2CO3-B2O3-V2O5时,在840℃烧结2h可制备出体积密度为4.99g/cm3的ZnO-TiO2陶瓷,达到理论密度的96.5%以上,εr、Q.f、τf分别约为24、22900GHz、-4×10-6/℃。

| Abstract: | Li2CO3-B2O3-V2O5-doping ZnO-TiO2 microwave dielectric ceramics were prepared by traditional so-lid-phase method,using Li2CO3,B2O3 and V2O5 as sintering additives,which are common low melting point oxides,and the behavior of sintering,phase composition,microstructure and microwave dielectric properties of ZnO-TiO2 ceramic were characterized or measured by means of XRD,SEM.As a result,the bulk density of ZnO-TiO2 ceramic doped with 3% addition of Li2CO3-B2O3-V2O5 sintered at 840℃ for 2h could get a higher value 4.99g/cm3,or over 96.5% of theoretical density,and εr,Q·f,τf were about 24,22900GHz,-4×10-6/℃. |
