Abstract

<abstract abstract-type="main" id="jace12880-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Novel glass–free low temperature firing microwave dielectric ceramics Li₂CeO₃ with high Q prepared through a conventional solid‐state reaction method had been investigated. All the specimens in this paper have sintering temperature lower than 750°C. XRD studies revealed single cubic phase. The microwave dielectric properties were correlated with the sintering conditions. At 720°C/4 h, Li₂CeO₃ ceramics possessed the excellent microwave dielectric properties of ε_{<italic>r</italic>} = 15.8, <italic>Q × f </italic>=<italic> </italic>143 700 (GHz), and τ_{<italic>f</italic>} = −123 ppm/°C. Li₂CeO₃ ceramics could be excellent candidates for glass‐free low‐temperature co‐fired ceramics substrates.</p> </abstract>
