(Ba_1-xHo_x)(Ti_1-xHo_x)O₃ceramics (BHTH) were prepared using the cold-pressing ceramic technique. The structure, site occupations, and dielectric properties of BHTH were investigated using X-ray diffraction (XRD), electron paramagnetic resonance (EPR) and dielectric-temperature measuring techniques. The results indicated that Ho³⁺ ions in the BaTiO₃ lattice could form a self-compensation mode with a slight Ba-site-occupation preference. The solubility limit was determined to be x = 0.03 in BHTH. The dielectric behavior of BHTH showed an abnormal phenomenon, i.e. that the Curie temperature (T_C) shifted towards high temperatures from 128 °C at x = 0.01 to 131 °C at x = 0.03. The increase in tetragonality (c/a) of the crystal structure of BHTH is the main reason of the increase in T_C.
