A high-purity hafnium material and a method for producing the material using a solvent extraction method. |
| abstract |
Hafnium-based materials are expected to be used as advanced electronic materials such as insulated gate materials, but it is difficult to separate zirconium with similar chemical properties, so high purity suitable for electronic material applications Hafnium materials could not be obtained in the past. The present invention can provide a high-purity hafnium material having a zirconium and other impurity elements of 1 ppm by weight or less and a method for producing the same by a method based on a solvent extraction method using a TBP solvent.
