Abstract
WHEN the hydrogen in potassium dihydrogen phosphate (KH2PO4) is replaced by deuterium by repeated crystallization from warm 99·6 per cent heavy water (D2O), the potassium phosphate separates in a different crystal structure. It can with some difficulty also be made to crystallize in the tetragonal form described by West1, by adding a nucleus of KH2PO4 to a supersaturated solution of KD2PO4. When the new crystal form is powdered, it slowly reverts to the tetragonal form over a period of days.
