产品详细介绍
TAN-1钽矿石成分分析标准物质Tantalum Ore
AN-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.
Recommended Value and 95% Confidence Interval

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.
