Uniaxial ferroelectric BaTi$$_2$$O$$_5$$ with a Curie temperature $$T_{rm C}$$ of 743 K was investigated to clarify its paraelectric-ferroelectric phase transition behavior. The mechanism is discussed on the basis of the structure from short to long ranges determined by synchrotron X-ray diffraction and the lattice dynamics probed by Raman spectroscopy. Using a combination of experimental results and first-principles calculations, we explain the phase transition. Ti vibration of TiO$$_6$$ octahedral units is frozen in the ferroelectric phase and the space group changes from nonpolar $$C2/m$$ to polar $$C2$$.
