General formula:
Cr2O3
N° standard / mount: 25 / MAC
Standard elements: Cr
Mineral class: Oxides
Synthetic: Yes
Locality: Supplier : Cerac
Comments:
The Cr2O3 used to prepare this standard is derived from fused material. As a result some blebs of chromium oxide glass do occur and these are shown as pale grey areas under the S.E.M. The darker patches seen are crystallised Cr2O3 and analysis should be confined to these areas.
