N2 - Abstract: A fine crystalline sample of the cubic modification (space group, Z = 16) of gadolinium oxide (C-Gd2O3) is grown by the solution–melt technique. The single crystal X-ray diffraction analysis performed at 150 K and 298 K reveals a relative increase in the unit cell parameter by 0.08%. The parameter at 300 K is refined by two independent procedures: in Bond’s scheme (a = 10.8152(9) Å, relative error Δa/a = 8·10–5) and by calibrating the equatorial circumference according to the external reference (a = 10.8145(6) Å, relative error Δa/a = 5.1·10–5). The values obtained coincide within the experimental error with data for the polycrystalline reference described by the National Bureau of Standards of the United States. The dependence a(T) is studied in the range of 90-490 K with a step of 10 K. Experimental points are described by second degree polynomial a = 10.801 + 2.7·10–5T + 6.0·10–8T2.
