Crystalline Structures, and Microwave Dielectric Properties of Low-Fired Li₂ZnTi₃O₈ Ceramics Doped with TLBBC

Abstract

low-fired Li₂ZnTi₃O₈ ceramics were fabricated by a solid-state reaction method for developing LTCC applications. TLBBC mixed sintering aid was used to improve the sintering stability. X-ray diffraction analyses demonstrated that specimens corresponded well to the cubic crystal symmetry structure of Li₂ZnTi₃O_8, accompanying with a little of impure phase Ca₃Ti₂O₇ and LiBO₂. The sintering temperatures of Li₂ZnTi₃O₈ ceramics were lowered to 950 °C due to the formation of low melting point LiBO₂. At x = 3, Li₂ZnTi₃O₈ ceramics exhibited an microwave dielectric properties with ε_r = 21.0, tanδ = 5.76 × 10⁻⁴, Q × f = 14750 GHz, τ_f = −11.5 ppm/°C at 950 °C.
