Özet
The solid-state reactions of Gd2O3 with NH4H2PO4 using various molar ratios (3:6, 2:8, 1:6 and 1:8) of the reactants were investigated at different temperatures (350-1100 degrees C) to observe the intermediate compounds. Analysis of the X-ray powder diffraction patterns of the products obtained at 350 degrees C; for the compositions of 2:8, 1:6 and 1:8 molar ratios revealed the formation of a new compound, NH4GdHP3O10 which was reported previously for Nd, Ho and Er. At higher temperatures, gadolinium tripolyphosphate was obtained for all of the molar ratios. On the other hand, the IR data of the products also confirmed the proposed reaction pathways.
