Nanocrystalline BaTiO3 powder was prepared by sol-gel process from tetrabuty ltitanium and hydrated barium hydroxide.The thermal decomposition reaction of the obtained gel has been studied by TG-DTA and FTIR techniques.The nano-powder had particle size of about 50 nm and was of cubic perovskite structure.The ceramics made from BaTiO3 nano-powder still maintained nano-scale microstructure with size of about 80~150 nm after sintering at 1190~1330℃.
