A critical comparison of X-ray powder diffraction data, combined with experimental work, shows that {open_quotes}monoclinic B-type{close_quotes} La{sub 2}O{sub 3} and Pr{sub 2}O{sub 3} 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{sub 9.33}(SiO{sub 4}){sub 6}O{sub 2} and Pr{sub 9.33}(SiO{sub 4}){sub 6}O{sub 2}, respectively. This confirms the currently acknowledged stability diagram of the rare earth sesquioxides.
