摘要：

Hydrothermal treatment of nanoscale amorphous ceric phosphate gel in KOH aqueous solutions was found to result in a new KCe2(PO4)3 phase. The refinement of the KCe2(PO4)3 structure showed that it was isostructural to recently reported (NH4)Ce2(PO4)3. For the KCe2(PO4)3 phase, the unit cell parameters Z = 4. The thermal decomposition of KCe2(PO4)3 at 800 degrees C resulted in the mixture of crystalline CePO4 and KPO3.
