Ceramic powder for 5G communication high-dielectric ceramic filter and preparation method of ceramic powder
The invention relates to the technical field of high-dielectric ceramics, and in particular, relates to ceramic powder for a 5G communication high-dielectric ceramic filter and a preparation method ofthe ceramic powder, wherein the ceramic powder for the 5G communication high-dielectric ceramic filter comprises the following raw material components: 96%-98.5% of BaTiO3 (barium titanate) and 1.5%-4% of a modifier, wherein the modifier comprises the following raw material components: 1%-3% of SrCO3 (strontium carbonate) and 0.5%-1% of Y2O3 (yttrium oxide). The preparation method comprises the following steps: A, powder proportioning; B, water milling; C, granulation; D, dry pressing molding; E, sintering; and F, surface treatment. Based on a solid-phase reaction method, through a series ofprocessing steps of powder proportioning, water milling, granulation, dry pressing molding, sintering and surface treatment, the microwave dielectric ceramic powder with high dielectric constant ([epsilon]r) and low dielectric loss (Q*F value) is prepared, so that the resonant filter has the characteristics of high inhibition, low insertion loss and good temperature drift characteristic, and the power capacity and passive intermodulation are improved.
本发明涉及高介陶瓷技术领域，尤其为5G通讯高介陶瓷滤波器用陶瓷粉体及制备方法，5G通讯高介陶瓷滤波器用陶瓷粉体，其原料组分如下，BaTiO（钛酸钡）：96%～98.5%、改性剂：1.5%～4%；所述改性剂中的原料组分如下，SrCO（碳酸锶）：1%～3%、YO（氧化钇）：0.5%～1%；包括以下步骤：A、粉体配比；B、水磨；C、造粒；D、干压成型；E、烧结；F、表面处理。本发明在固相反应法的基础上，通过粉体配比、水磨、造粒、干压成型、烧结、表面处理这一系列的加工，制成具有高介电常数（εr）和低介质损耗（Q×F值）的微波介质陶瓷粉体，从而使得谐振滤波器具有抑制高、插入损耗小、温度漂移特性好的特点，并改善了功率容量和无源互调性。
