摘要:	The bulk dense nanoceramics BaTiO3 of grain size less than 100nm were prepared by the spark plasma sintering method. Raman spectroscopy revealed the dispersive phase transition character in the nanocrystalline BaTiO3 apectroscopy revealed the dispersive phase transition character in the nanocrystalline BaTiO3 ceramics. The BaTiO3 ceramics of the nanograin of 15 nm exhibited the similar phase transfirmations from rhombohedral to orthorhombic to tetragonal to cubic tranitions as those in the coarse BaTiO3 ceramics.
