Streszczenie: The monoclinic B-modification of lutetium and ytterbium sesquioxides was obtained by high pressure high temperature (P=5.0 GPa, T=1000 C, 1300 C) treatment of cubic C-RE2O3 (RE=Yb, Lu) in toroid-type high pressure apparatus. X-ray data from materials were collected in Imaging Plate Guinier Camera G670 (Huber). The procedure of full profile Rietveld analysis was performed with the help of GSAS (General Structure Analysis System) to get the structural information, which can be used in structure data base. The unit cell dimensions are as follows: Lu2O3, a=13.6903(2), b=3.41261 (5), c=8.4422(1) Å, ȕ=100.171(1)º; Yb2O3, a=13.7056(1) , b=3.43146(3), c=8.4730(1) Å , ȕ=100.157(1)º. A new high pressure phase of lutetium and ytterbium sesquioxides was found in the samples after treatment at P=5.0 GPa, T=1000 C.
