Abstract
The invention discloses a method for synthesizing titanium dioxide nanometer powder at low temperature, and belongs to the technical field of material powder preparation. In this method, titanyl sulfate is first dissolved in an appropriate amount of deionized water containing organic additives, stirred evenly, and then the solvent is evaporated and concentrated to obtain a uniform solid mixture containing titanium and organic additives; the solid mixture is gradually added to an appropriate excess of hydroxide Stir, grind and mix in sodium. The mixing material is washed with deionized water and left to stand to obtain a precipitate, which is then filtered, washed with water, dried and calcined to obtain a high-purity titanium dioxide nano-powder with good dispersibility. The method of the invention has the advantages of simple and easy controllable process parameters, uniform particle size, adjustable particle size, resource saving, little pollution and the like.
