Description
技术领域
本发明属于微波介质陶瓷技术领域,更具体地,涉及一种硅基低介微波介质陶瓷及其制备方法。
背景技术
微波介质陶瓷是指应用于微波频段(300MHz~300GHz)电路中作为介质的陶瓷材料。随着通信设备运行频率不断的提高,信号延迟现象会变得更加明显,***损耗和发热量也会随之增大,***稳定性会逐渐变差。而低介电常数能减小材料与电极之间的交互耦合损耗,并且能提高电信号的传输速率,优异的品质因数能减小***损耗且会提高材料的选频特性。考虑到环境友好和低成本等因数,硅基低介电常数的微波介质陶瓷的研究显得尤为重要。
多层陶瓷电容器(Multi-layer ceramic capacitors,简称MLCC)是一种广泛应用于表面贴装技术中的元器件,作为电子行业的基础原件,MLCC的需求量近年来以每年10%左右的递增,但MLCC的出口量90%以上都来自日本、美国等国家。MLCC按照内电极的种类可分为贵金属内电极多层陶瓷电容器(Precious Metal Electrode,简称PME-MLCC)和贱金属内电极多层陶瓷电容器(Base Metal Electrode,简称BME-MLCC)。PME-MLCC采用价格昂贵的Ag或Ag-Pd电极,可以在空气中烧结。而BME-MLCC通常采用相对廉价的Cu或Ni电极,BME-MLCC的价格相对较低但需要在还原性气氛中烧结。较低的生产成本和稳定的生产工艺是我国MLCC领域需要努力的目标。
为了制备出有竞争力的MLCC产品,研究出一种能抗还原(不含易变价元素)、价格低廉(富含Si、Ba、Ca等)且烧结温度在Cu或Ni电极熔点以下的微波介质陶瓷显得尤为重要。

步骤(2):将步骤(1)得到的预烧陶瓷粉体,进行二次湿法球磨处理,烘干后加入粘合剂造粒,压片后进行烧结,获得所述微波介质陶瓷。
优选地,步骤(1)所述湿法球磨处理,湿法球磨分散剂为300wt%的去离子水和介质为锆球,球磨工艺为以360r/min的速度球磨5小时。
优选地,步骤(1)所述预烧的温度为1000℃~1100℃,预烧时间为5~10小时。
