Effects of BaCu(B₂O₅) additives on the crystal structures and dielectric properties of CaMgGeO₄ ceramics for LTCC applications

Abstract

<p>A CaMgGeO₄ (CMG) ceramic with an olivine structure was fabricated by the traditional solid-phase reaction method; this material was dense at 1300 °C/6 h and exhibited excellent dielectric properties (<italic>ε</italic>_r = 6.83, <italic>Q</italic> × <italic>f</italic> = 125 432, <italic>f</italic> = 14.9 GHz).</p>
