摘要：

A critical comparison of X-ray powder diffraction data, combined with experimental work, shows that ''monoclinic B-type'' La2O3 and Pr2O3 described in the literature are in fact rare earth silicates of the hexagonal apatite-type structure. A comparison of X-ray powder data reveals that both compounds are identical with La-9.33(SiO4)(6)O-2 and Pr-9.33(SiO4)(6)O-2, respectively. This confirms the currently acknowledged stability diagram of the rare earth sesquioxides. (C) 1995 Academic Press, Inc.
