Dear colleagues, does anybody know a fine-grained alumina (corundum) material with high purity, suitable for using as internal standard in quantitative phase analysis, as an economic alternative for the NIST SRM 676a? In the past we used American Elements AL-OX-03-S (spray-dried) what worked quite well, but this is out of stock now and substituted by AL-OX-03M-PSP (plasma-sprayed). Are there any experiences with plasma-sprayed corundum products? Thanks in advance Reinhard -- TU Bergakademie Freiberg Dr. R.
