By extraordinary coincidence, this week I have been collecting a data set of
Y2O3 for the first time in nine years. It is a remarkable material by virtue of
the fact that one still gets reasonable intensities as high as 167 deg 2 theta.

Ian is correct when he says it is improved by annealing. In this case, heating
it to 1200 deg C for 3 days reduced the peak widths from 0.16 to 0.07 deg two
theta.

P.S. I do not advocate "teaching ones grandmother to suck eggs" but don't
expect the Inel to resolve the peaks as well as this.
