| Abstract: | The growth of neodymium tartrate crystals was achieved in silica gel by single diffusion method. Optimum conditions were established
for the growth of good quality crystals. Fourier transform infrared (FT-IR) spectroscopic study indicates the presence of
water molecules and tartrate ligands and suggests that tartrate ions are doubly ionised. The thermal behaviour of the material
was studied using thermogravimetry (TG), differential thermal analysis (DTA), derivative thermogravimetry (DTG) and differential
scanning calorimetry (DSC). Thermogravimetric analysis support the suggested chemical formula of the grown crystal to be Nd2(C4H4O6)3·7H2O, and the presence of seven water molecules as water of hydration. It is shown that the material is thermally stable up 45 °C
beyond which it decomposes through many stages till the formation of neodymium oxide (Nd2O3) at 995 °C. The decomposition pattern is reported to be typical of a hydrated metal tartrate. |
