    Abstract

    Spherical aggregates of leaf-like YPO 4 particles have been prepared by the reactions of tri-n-butylphosphate [PO(OC 4H 9) 3, TBP] with the acidic Y(NO 3) 3 aqueous solution in an autoclave at 180°. The products of the reactions for 1, 3 and 6 h consisted of an intermediate exhibiting an intense X-ray diffraction line at d μ 1.28 nm, while those of reactions for 1248 h were pure YPO4. The products of the reactions for 8 and 8.5 h were mixtures of the intermediate and YPO 4. YPO 4 formation thus seems to proceed via the formation of the intermediate. Since the intermediate seems to be Y[PO 2(OC 4H 9) 2] 3, it is likely that TBP was hydrolyzed to form PO 2(OC 4H 9) 2- ions, which then reacted with Y 3+ ions to form the solid intermediate, Y[PO 2(OC 4H 9) 2] 3. Scanning electron microscopy (SEM) revealed the corresponding morphological change from the belt-like products to spherical aggregates of leaflike particles, indicating that the solid intermediate Y[PO 2(OC 4H 9) 2] 3 was hydrolyzed to form leaf-like YPO 4 particles.
