- Abstract
Microwave ceramic with low‐sintering temperature is one of the most significant classes of materials to realize the multifunction and miniaturization of portable devices. In this paper, Bi6B10O24 ceramics using the solid-state reaction method are prepared with MoO3 addition, to achieve both low-temperature sintering and excellent microwave dielectric properties. It is demonstrated that MoO3 diffuses into the lattice of Bi6B10O24 to form a solid solution. The higher quality factor (Q × f) of the ceramic is successfully obtained and the temperature coefficient of resonant frequency (τf) is adjusted to near zero at the same time without much change in the dielectric constant (εr) due to the Mo6+ incorporation. Compared to Bi6B10O24 ceramics without addition, the optimum properties of εr = 13.9, Q × f = 37,000 GHz, τf = − 20 ppm/°C are achieved for Bi6B10O24 ceramics containing 19 mol% MoO3. The ceramics are potential candidates for ultra-low temperature co-fired ceramics (ULTCC) applications in wireless communication systems.
