An Absolute Measurement of the Susceptibility of Tantalum and other Metals

Abstract

The magnetic susceptibility of tantalum has been determined absolutely, the value obtained for the mass susceptibility being XTax106=0.8490±0.0006 at 20° C. Small specimens of tantalum have been used to determine, by a comparative method, the susceptibilities of specimens of platinum, palladium and rhodium at 20°C. The values obtained are · XPtx106=0.9712±0.0007, X Pdx106=5.231±0.004, XRh×106=0.9903±0.0008. All specimens were prepared from spectrographically standardized materials.
