Preparation method of low-dielectric low-loss zinc magnesium silicate system microwave dielectric ceramic
The invention relates to a preparation method of low-dielectric-constant low-loss zinc magnesium silicate system microwave dielectric ceramic. According to the method, Zn2SiO4 ceramic is used as a matrix, Mg < 2 + > is adopted for doping and substitution, ZnO, MgO and SiO2 are mixed according to the stoichiometric ratio of the chemical formula (Zn1-xMgx) 2SiO4, x is 0.6-0.8, and the Zn2SiO4-Mg2SiO4 two-phase composite microwave dielectric ceramic is synthesized through a traditional solid-phase reaction method. The compactness of the sample is improved through two-phase compounding, so that the prepared (Zn1-xMgx) 2SiO4 has a low dielectric constant and low dielectric loss, and the sintering temperature of the ceramic sample is reduced. The invention can provide an alternative material for microwave communication components such as resonators, filters and the like, and has wide application prospects.
本发明涉及一种低介电常数低损耗硅酸锌镁体系微波介质陶瓷的制备方法。本发明的方法以Zn2SiO4陶瓷为基体，采用Mg2+掺杂取代，将ZnO、MgO和SiO2按化学式(Zn1‑xMgx)2SiO4的化学计量比进行配料，其中x＝0.6～0.8，通过传统固相反应法合成了Zn2SiO4‑Mg2SiO4两相复合的微波介质陶瓷。两相复合提高了样品的致密性，使得制备出的(Zn1‑xMgx)2SiO4具备低的介电常数和低的介电损耗，并且降低了陶瓷样品的烧结温度。本发明可以为谐振器和滤波器等微波通讯元器件提供一种备选材料，具有广阔的应用前景。
