Abstract:
An yttrium oxyfluoride is represented by YOF and is stabilized by a fluoride represented by CaF 2 . Preferably, the number of moles of Ca with respect to 100 mol of yttrium is from 8 to 40 mol. A powder material is made of a first powder mixture including a calcium fluoride powder represented by CaF 2  and an yttrium oxyfluoride powder represented by YOF, or a second powder mixture including a calcium fluoride powder represented by CaF 2 , an yttrium fluoride powder represented by YF 3 , and an yttrium oxide powder represented by Y 2 O 3 . A production method involves firing a molded product of the first or second powder mixture under predetermined conditions.

Claim (Index 7):
An yttrium oxyfluoride represented by YOF, the yttrium oxyfluoride being stabilized by a calcium fluoride represented by CaF 2 , wherein, when the yttrium oxyfluoride is subjected to powder X-ray diffraction measurement at 25\u00b0 C. within a range 2\u03b8=10\u00b0 to 90\u00b0 by employing a CuK\u03b11 line as a radiation source, the yttrium oxyfluoride satisfies (A) or (B) below:\n (A) on the premise that no XRD peak caused by YOF other than cubic and rhombohedral crystals is observed, no reflection peak from a (003) plane of a rhombohedral YOF is observed at around 2\u03b8=14\u00b0; or \n (B) a main peak of a cubic YOF is observed at 2\u03b8=28.81\u00b0, and the height of a reflection peak from a (003) plane of a rhombohedral YOF observed at around 2\u03b8=14\u00b0 is less than one one-hundredth of the peak height of the main peak of the cubic YOF.
