Abstract
The results of an investigation dealing with pure ammonium perrhenate synthesis from crude ammonium perrhenate by multi-stage recrystallization are presented. It is shown that it is impossible to produce ammonium perrhenate of the AP-00 grade with the permissible potassium impurity level using this method. Recommendations for synthesis of the salt of the AP-0 grade are given.
