Title:
ナノメートル二酸化チタンを調製するための方法
Document Type and Number:
Japanese Patent JP6268328
Kind Code:
B2
Abstract:
The present invention belongs to the field of preparation technique of inorganic functional material and provides a method for preparing nanometer titanium dioxide which comprises the following steps: (1) dissolving ilmenite powder using hydrochloric acid to obtain a raw ore solution; (2) eliminating the iron element in the raw ore solution to obtain a final solution containing titanium ions; (3) heating the final solution for hydrolysis to obtain a hydrolyzed product containing titanium dioxide; and (4) calcining the obtained hydrolyzed product to obtain nanometer titanium dioxide. The present invention has the advantages that the raw materials can be easily obtained, the energy consumption is low, both rutile type titanium dioxide and anatase type titanium dioxide can be produced, and the product has high purity, small particle diameter, narrow particle diameter distribution and good dispersibility.
