Abstract

A series of low-permittivity LiAl1 − xBxO2 (0.01 ≤ x ≤ 0.10) ceramics were fabricated by a conventional solid-state reaction method and were characterized for their phase evolution, crystal structure, and dielectric properties. Single-phase LiAl1 − xBxO2 solid solutions were formed at a limited compositional range (x = 0.05) while the secondary phase Li2(BAlO4) companied at higher dopant contents. Boron substitution facilitated the sintering behavior and optimized the densification of LiAlO2, resulting in dense microstructures and improved dielectric properties. A composition with x = 0.075 exhibited a high quality factor (Q×f) of 40,288 GHz along with a low relative permittivity (εr) of 6.3 and a temperature coefficient of resonance frequency (τf) of – 191 ppm/oC. All results indicate that the LiAl1 − xBxO2 ceramics can be a promising candidate material in the application of the substrate.
