Synthetic Iron Ore Calibration Standard

Manufactured from high purity synthetic compounds according to ISO 9516-1:2003(E) with the extra addition of NaCl and compensating decrease of SiO2.

The ISO method 9516 does not include sodium or chlorine but these elements were requested by the iron ore industry. The NaCl was dried at 105 degrees C before addition. The above analytical information is the average of 10 XRF determinations carried out and verified by CSIRO Minerals, South Australia.

* The SD was derived from the homogeneity test work.
