| Ein Beitrag zur Kristallchemie dreiwertiger Seltenerdoxide Zur Stabilisierung der m onoklinen B-Form  | | | Abstract
| Single crystals of 1 — a'Ho203 : xCaO (x = 0.07), CaHoC>2.5 (A) and Cao.5H 01.5O2.75 (B) were prepared by high temperature reaction and investigated with X-ray single crystal data. It can be shown that small amounts of CaO stabilize the monoclinic B-Typ of rare earth oxides. Phase (A) and (B) cannot be seen as a stabilized B-type crystal because they have an new crystal structure with space group C.7h-P 2 i/m, a = 656.6, b = 356.7, c = 529.4pm , ß = 92.3°; a = 650.2, b = 352.4, c = 584.5, ß = 92.3°. | | |
