Medium-temperature sintered low-dielectric low-loss microwave dielectric ceramic material as well as preparation method and application thereof
The invention discloses a medium-temperature sintered low-dielectric low-loss microwave dielectric ceramic material as well as a preparation method and application thereof. The medium-temperature sintered low-dielectric low-loss microwave dielectric ceramic material comprises a principal crystalline phase and doped cations, the chemical formula of the main crystal phase is (1-x-y)/2Mg2SiO4-yMgSiO3-xMgTi2O4, x is more than or equal to 0.15 and less than or equal to 0.27, and y is more than or equal to 0.28 and less than or equal to 0.37; the doped cations comprise at least one of barium ions, calcium ions, strontium ions, aluminum ions, zinc ions, lanthanum ions, niobium ions and bismuth ions; magnesium ions, aluminum ions, zinc ions, lanthanum ions, niobium ions and bismuth ions in the principal crystalline phase are replaced by barium ions, calcium ions and strontium ions to replace magnesium ions, silicon ions or titanium ions in the principal crystalline phase. By adding other cations to replace magnesium ions, silicon ions or titanium ions in the principal crystalline phase, lattice distortion of the principal crystalline phase is achieved, and therefore the temperature needed by synthesis of the principal crystalline phase is reduced.
本发明公开了一种中温烧结低介低损耗微波介质陶瓷材料及其制备方法和应用，中温烧结低介低损耗微波介质陶瓷材料包括主晶相和掺杂阳离子；所述主晶相的化学式为：(1‑x‑y)/2Mg2SiO4‑yMgSiO3‑xMgTi2O4，其中0.15≤x≤0.27，0.28≤y≤0.37；掺杂阳离子包括钡离子、钙离子、锶离子、铝离子、锌离子、镧离子、铌离子以及铋离子中至少一种；钡离子、钙离子以及锶离子取代主晶相中的镁离子，铝离子、锌离子、镧离子、铌离子以及铋离子取代主晶相中的镁离子、硅离子或钛离子。通过加入别的阳离子取代主晶相中的镁离子、硅离子或钛离子，使得主晶相的晶格畸变，从而降低主晶相合成所需的温度。
