Abstract
Y2O3 ceramics with good dielectric properties were prepared via co-precipitation reaction and subsequent sintering in a muffle furnace. The effects of Nd doping and sintering temperature on microwave dielectric properties were studied. With the increase in sintering temperature, the density, quality factor (Q×f), and dielectric constant (εr) values of pure Y2O3 ceramics increased to the maximum and then gradually decreased. The Y2O3 ceramics sintered at 1500°C for 4h showed optimal dielectric properties: εr=10.76, Q×f=82, 188GHz, and τf=−54.4ppm/°C. With the addition of Nd dopant, the Q×f values, εr, and τf of the Nd: Y2O3 ceramics apparently increased, but excessive amount degraded the quality factor. The Y2O3 ceramics with 2at% Nd2O3 sintered at 1460°C displayed good microwave dielectric properties: εr=10.4, Q×f=94, 149GHz and τf=−46.2ppm/°C.
