Preparation and dielectric properties of La doped NBCCTO ceramics

Effect of UV irradiation on the densification behavior, microstructure, and microwave dielectric properties of low temperature sintering Al2O3 ceramics

“…One is the grain size and its uniformity. Many investigations show that larger grain size and higher uniformity are helpful to the increasing of Q × f value [ [17] , [18] , [19] , [20] , [21] ]. Another is the impure phase.…”
