In the search of more microwave dielectric materials with high-quality factor (Q×f) and high relative dielectric constant (ε_r), RENbO_4 (where RE = Y, Ce, Yb) niobate ceramics were synthesized from a solid-state ceramic route, their sintering behavior and microwave dielectric properties were investigated. All of the RENbO_4 ceramics formed a single-phase fergusonite-type structure (monoclinic, with space group 12/c), except CeNbO_4. They all have an excellent quality factor and dielectric constant value in range of 20 - 28, and the inherent reasons were analyzed.
