Pure and Mn-doped barium hafnate titanate ceramics (BaHf 0.1 Mn  x  Ti 0.9  –   x  O 3 , where  x  = 0, 0.02, 0.05, 0.08, and 0.1) are prepared by means of a sol–gel method. The microstructures, dielectric properties and ferroelectric properties of the ceramics are investigated. X-ray diffraction patterns indicate that Mn 4  +  ions enter the unit cell to maintain the perovskite structure of solid solution. Consequently, the tetragonality gradually decreases with increased Mn content. The grains of Mn-doped BaHf 0.1 Ti 0.9 O 3  ceramics become uniform and almost spherical. The diffuseness constant decreases from 1.89 to 1.48 with increased Mn content from 0 at.% to 5 at.%. Hysteresis loops can be observed in all samples from 30 °C to 90 °C, which may be due to the relaxor ferroelectric property of these ceramics.
