The tetragonal phase stability of (Ba1-xPrx)(Ti0.99Mn0.01)O3 ($x = 0, 0.01, 0.02$) ceramics prepared using a cold-pressing ceramic technique was investigated by X-ray diffraction (XRD), electron spin resonance (ESR), scanning electron microscopy (SEM), and dielectric measurements. Tetragonal and hexagonal phases coexist at $x = 0$, but at $x = 0.02$, the hexagonal phase disappears and the tetragonal phase is completely stabilized by the appearance of Mn2+. Co-doped Pr ions serve as a tetragonal phase stabilizer for Mn-doped BaTiO3.
