註釋Resistivities of small specimens of 5Co-15Rh80Pt, 5Cr-15Rh-80Pt, 10Cr-15Rh-75Pt, and 5Ru15 Rh-80Pt were determined for temperatures up to 900 C. Resistance to progressive oxidation was observed in the Co- and Cr-containing alloys. The Co-containing alloy exhibited a shallow minimum of resistivity between about 200 and 400 C, but stability was not attained. The Cr-containing alloys exhibited very high and nearly constant rates of change of resistivity with temperature up to low-temperature reversible transformation points and were electrically stable at all temperatures. The Ru-containing alloy exhibited a linear and stable change of resistivity throughout its (lower) useful temperature range. (Author).
