Dear Stephen, I have prepared XPD-standard Y2O3 by firing Y2O3 (99.999) from Aldrich at 1200 �C for 72 hs. (as done in 41-1105 PDF card). I would also like to ask the other list members if anyone has calibrated the size-strain broadening of Y2O3 against LaB6, because I have no access to LaB6 and I've heard that yttria gives broader lines. Thanks Leopoldo

I need few grams of these for calibration of our XRD. Thank in advance. regards stephen
