TAN-1 Certificate of Analysis
Certified Reference Material: Tantalum Ore
Printable version of the certificate (PDF, 699.33 kb)
TAN-1 is a sample of tantalum ore typical of the deposit at Bernic Lake, Manitoba. The tantalum occurs in wodgenite and microlite, which are found in zones of partially sericitized perthitic microcline and of relatively unaltered, fine-grained, bluish-white aplitic albite in the pegmatite deposit. The deposit has been characterized mineralogically in detail at CANMET.
|Ta||0.236 ± 0.005|
|Ta2O5||0.288 ± 0.006|
Nineteen laboratories provided results for tantalum by X-ray fluorescence, DCP-emission spectrometry, ICP-atomic emission spectrometry, colorimetry, atomic absorption spectrometry, and gravimetry.
A certificate of analysis will be issued with each order of TAN-1. A copy of CANMET Report 83-10E, "TAN-1: A certified tantalum reference ore", will be forwarded, free of charge, on request to the Coordinator, CCRMP.
