    摘要:

    采用传统固相反应法制备Zn2Te3O8 30%TiTe3O8(ZTT,质量分数)粉体,在低于600 ℃的管式气氛炉中烧结,利用XRD、SEM及微波网络分析仪等手段对不同热处理后的样品进行分析,并测试介电性能。实验表明,ZTT能在超低温下烧结成瓷,且介电性能良好(低频测试下介电常数εr=19~27,损耗低于3%,高频下品质因数与频率之积Q×f=56 191 GHz,频率温度系数τf=1.66 μ℃-1),为制作低成本薄膜电容提供可能。

    Abstract:

    The Zn2Te3O8-30%TiTe3O8(ZTT) powder was prepared using the solid state reaction technique, and sintered at temperature low than 600 ℃ in atmosphere furnace. Then the samples were analyzed by XRD, SEM and microwave network analyzer. The result showed that ZTT could be sintered in ultra low temperature with pretty good dielectric properties(at 1 MHz measured frequency, the dielectric constant and the dielectric loss were 19~27 and low than 3%, respectively,at high frequency,the Q×f and τf of ZTT ceramics were 56 191 GHz and 1.66 μ℃-1, respectively).Thus it was possible to produce low cost thin film capacitance.
