Temperature-stable microwave dielectric ceramic as well as preparation method and application thereof
The invention discloses a temperature-stable microwave dielectric ceramic, which is prepared by sintering a main material and an auxiliary material. The chemical structural formula of the main material is Mg2Al4Si5O18, the chemical structural formula of the auxiliary material is Zr0.6Sn0.4TiO4, and the chemical expression of the microwave dielectric ceramic is (100-x) wt% Mg2Al4Si5O18-x wt% Zr0.6Sn0.4TiO4, relative to the total amount of the main material and the auxiliary material, the mass percent of the auxiliary material is x wt%, and x is greater than or equal to 1 and less than or equal to 10. The invention also discloses a preparation method and application of the temperature-stable microwave dielectric ceramic. The microwave dielectric ceramic provided by the invention has excellent microwave dielectric properties, not only improves the quality factor to a certain extent, but also has better temperature stability at high temperature and low temperature, has a lower dielectric constant, and has wide application prospects.
本发明公开了一种温度稳定型微波介质陶瓷，该微波介质陶瓷是由主料和辅料烧结而成，主料的化学结构式为Mg2Al4Si5O18，辅料的化学结构式为Zr0.6Sn0.4TiO4，该微波介质陶瓷的化学表达式为(100‑x)wt％Mg2Al4Si5O18‑x wt％Zr0.6Sn0.4TiO4；相对于主料和辅料的总量，辅料的质量百分比为x wt％，1≤x≤10。本发明还公开了该温度稳定型微波介质陶瓷的制备方法和应用。本发明的微波介质陶瓷具有优异的微波介电性能，其不仅在一定程度提高了品质因数，且在高温和低温时都具有较好的温度稳定性，又具有较低的介电常数，具有广泛的应用前景。
