A high Q and temperature stable microwave dielectric ceramic Ba4LiTa2SbO12
Source abstract
Abstract
Abstract A low loss and temperature stable microwave dielectric ceramic Ba 4 LiTa 2 SbO 12 with 8H hexagonal perovskite structure was prepared by traditional solid-state ceramic route. Sintering behavior, phase transformation, and microwave dielectric properties of Ba 4 LiTa 2 SbO 12 ceramics were studied. X-ray diffraction analysis indicated that a phase transition from cubic to hexagonal perovskite occurred when calcined temperature increased from 1300 °C to 1500 °C. Ba 4 LiTa 2 SbO 12 ceramic sintered at 1480 °C exhibited optimum microwave dielectric properties with a moderate relative permittivity of ~25.1, a high quality factor ( Q u × f ) of ~77,700 GHz, and a near zero temperature coefficient of resonant frequency ( τ f ) of −3.6 ppm/°C.
