Abstract
A BSTRACT Hydrothermal treatment of nanoscale amorphous ceric phosphate gel in KOH aqueous solutions was found to result in a new KCe 2 (PO 4 ) 3 phase. The refinement of the KCe 2 (PO 4 ) 3 structure showed that it was isostructural to recently reported (NH 4 )Ce 2 (PO 4 ) 3 . For the KCe 2 (PO 4 ) 3 phase, the unit cell parameters (sp. gr. C 2 /c ) were a = 17 . 3781(3) ˚A, b = 6 . 7287(1) ˚A, c = 7 . 9711(2) ˚A, β = 102 . 351(1) ◦ , V = 910 . 53(4) ˚A 3 , Z = 4 . The thermal decomposition of KCe 2 (PO 4 ) 3 at 800 ◦ C resulted in the mixture of crystalline CePO 4 and KPO 3 .
