Abstract:  Sc₂O₃ (5.1 g.) was dissolved in a slight excess of 1:1 HCl, the soln. filtered, dild. with H₂O to 250 ml. and 10.1 g. KH₂PO₄ (dild. to 250 ml. with H₂O) added with stirring. The pH was adjusted to 4 with NaOAc soln. The white ppt. of ScPO₄.xH₂O (where x ∼3.2) was characterized using GTA, DTA, x-ray powder method, and infrared spectroscopy. Adsorbed H₂O (not crystal lattice H₂O) was evolved at 20-350° to give ScPO₄. Heating at 800-30° causes formation of amorphous ScPO₄.
