Hi all
I was hoping someone could help me identify a REE oxide mount I found tucked away that I have somehow missed over the years. It is labelled "P&H REE2O" and has six glasses mounted on it. As far as I can determine from EDS, their element content is as follows:
1) Pure Si-Al-Ca glass - no REE
2) Si-Al-Ca glass +Nd-Tb-Lu
3) Si-Al-Ca glass +La-Sm-Ho-Yb
4) Si-Al-Ca glass +Ce-Eu-Ho-Tm
5) Si-Al-Ca glass +Pr-Dy-Er
6) Another Pure Si-Al-Ca glass - no REE? Not sure why there would be two blanks on this mount though, perhaps just low level and not detectable by EDS?
I have the other P&H single element Ca-Si-Al REE standards, but nowhere can I find any information on these multi-element P&H REE xtals. Is anyone able to shed any light on these, were they distributed or custom made, is there any certified numbers for them?
Cheers
