Preparation method of low-temperature high-Q low-loss dielectric material for MLCC (multilayer ceramic capacitor)
The invention relates to the technical field of ceramic dielectric materials, in particular to a preparation method of a low-temperature high-Q low-loss dielectric material for an MLCC (multilayer ceramic capacitor), which comprises the following steps: carrying out primary weighing, ball-milling and mixing on high-purity ZnO, MgO and TiO2 according to a ratio, calcining to obtain a pre-sintered material, adding a sintering aid into the pre-sintered material, carrying out secondary ball-milling to refine the particle size of reactants, and sintering to obtain the low-temperature high-Q low-loss dielectric material for the MLCC. The ceramic powder subjected to secondary ball milling is granulated and pressed into a cylindrical green body, and finally the green body is degummed and sintered. Compared with the prior art, the prepared MLCC electronic ceramic material has good electrical performance parameters, can meet the use requirements of an MLCC technology, has lower sintering temperature, can meet the use requirements of a matched low-resistance electrode material Cu and the like, and is low in raw material price, low in sintering temperature, free of environmental pollution and suitable for industrial production. And an effective selection scheme is provided for high-frequency, integrated, high-density, high-speed and high-reliability development of electronic components.
本发明涉及陶瓷介质材料技术领域，特别涉及一种MLCC用低温高Q低损耗介质材料的制备方法，通过将高纯度ZnO、MgO、TiO2按照配比进行一次称量球磨混合，通过煅烧得到预烧料，再向预烧料中加入助烧剂进行二次球磨细化反应物颗粒尺寸，将二次球磨后的陶瓷粉进行造粒，压制成圆柱状生坯，最后生坯排胶烧结而成。与现有技术相比，本发明制得的MLCC电子陶瓷材料具有良好的电性能参数，能满足MLCC技术使用需求，并具有较低烧结温度能够满足与匹配的低电阻电极材料Cu等使用要求，制备工艺采用原材料价格低廉、烧结温度低、对环境无污染，为电子元器件向高频化、集成化、高密度、高速度、高可靠性发展提供了有效的选择方案。
