Single-phase samarium titanate nano-powder prepared by using solution method, and method for preparing single-phase samarium titanate nano-powder

摘要: The invention relates to single-phase samarium titanate nano-powder prepared by using a solution method, and method for preparing the nano-powder. comprisesthe following steps: firstly dispersing source titanium into solvent according molar ratio of 1 (1.1-1.3) obtain A; adjusting pH value A be neutral milk-white mixed B; separating B white powder; drying powder obtained in third step, then calcining According aim accurately controlling stoichiometric ternary Sm-Ti-O chemical elements is achieved fully dissolving medium as well mixing reacting at an atomic scale, so that other impurities are prevented from appearing, Sm2Ti2O7 further realized.
