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 9):
The yttrium oxyfluoride according to  claim 7 , wherein, when the yttrium oxyfluoride is subjected to TMA measurement wherein the temperature is raised/lowered between 25\u00b0 C. and 1000\u00b0 C. at a temperature rise/drop rate of 5\u00b0 C./min, no point of discontinuity in dimensional change caused by phase transition is observed within the measurement range (wherein: \u201chaving a point of discontinuity in dimensional change\u201d means that two inflection points are observed during temperature rise or temperature drop; when a low-temperature-side point of the two inflection points is defined as T1 and a high-temperature-side point is defined as T2, a tangent line of a TMA curve at a point that is 10\u00b0 C. toward the low-temperature side than T1 and a tangent line of the TMA curve located at the center between T1 and T2 intersect only at one intersection point and do not have the same inclination).
