Abstract

Ultra-low permittivity (εr:4–5) Mg2Al4–x(Ge0.5Mg0.5)xSi5O18 (0.12 ≤ x ≤ 0.28) and Mg2Al4–y(Mn0.5Mg0.5)ySi5O18 (0.1 ≤ y ≤ 0.3) cordierite ceramics were fabricated by solid-state reaction method. The improvement in [(Si4Al2)O18] hexahedral ring roundness significantly enhances the quality factor through the substitution of complex ionic pairs of Ge0.5Mg0.5/Mn0.5Mg0.5 for Al lattice sites in the [(Si4Al2)O18] hexahedral ring of these cordierite ceramics. Excellent microwave dielectric performances of Mg2Al3.8(Ge0.5Mg0.5)0.2Si5O18 and Mg2Al3.8(Mn0.5Mg0.5)0.2Si5O18 ceramics sintered at 1400 °C were demonstrated using the Hakki-Coleman resonant method with εr = 4.676, Q×f = 186, 503 [email protected] GHz and 199,476 GHz @ 27.434 GHz, τf = −20.02 ppm/°C and εr = 4.807, Q×f = 101,420 [email protected] GHz and 143,005 GHz @ 27.366 GHz, τf = −26.44 ppm/°C, respectively. These results present the potential application of high-quality cordierite in future B5G/6 G millimeter and terahertz communication frequency bands.

显著增强堇青石陶瓷的微波毫米波特性:硅-铝六角环的圆度调节,远红外反射率和太赫兹时域光谱分析
利用固态反应法制备了超低介电常数(εr:4-5)Mg2Al4-x(Ge0.5Mg0.5)xSi5O18(0.12 ≤ x ≤ 0.28)和 Mg2Al4-y(Mn0.5Mg0.5)ySi5O18(0.1 ≤ y ≤ 0.3)堇青石陶瓷。通过在这些堇青石陶瓷的[(Si4Al2)O18]六面体环中用Ge0.5Mg0.5/Mn0.5Mg0.5的复杂离子对取代Al晶格位点,[(Si4Al2)O18]六面体环的圆度得到改善,从而显著提高了品质因数。利用哈基-科尔曼谐振法,在 1400 °C 下烧结的 Mg2Al3.8(Ge0.5Mg0.5)0.2Si5O18 和 Mg2Al3.8(Mn0.5Mg0.5)0.2Si5O18 陶瓷具有优异的微波介电性能,εr = 4.676, Q×f = 186, 503 [email protected] GHz and 199,476 GHz @ 27.434 GHz, τf = -20.02 ppm/°C 和 εr = 4.807, Q×f = 101,420 [email protected] GHz and 143,005 GHz @ 27.366 GHz, τf = -26.44 ppm/°C。这些结果展示了高品质堇青石在未来 B5G/6 G 毫米和太赫兹通信频段中的潜在应用。

期刊介绍: The Journal of the European Ceramic Society publishes the results of original research and reviews relating to ceramic materials. Papers of either an experimental or theoretical character will be welcomed on a fully international basis. The emphasis is on novel generic science concerning the relationships between processing, microstructure and properties of polycrystalline ceramics consolidated at high temperature. Papers may relate to any of the conventional categories of ceramic: structural, functional, traditional or composite. The central objective is to sustain a high standard of research quality by means of appropriate reviewing procedures.
