Abstract
The electrical resistivity, thermal diffusivity, and Seebeck coefficient of niobium have been measured from 300°–1200°K. Using measured values of thermal diffusivity and literature values of specific heat, the thermal conductivity has been calculated for the same temperature range. The Lorenz number is 2.75 ×10−8 W-Ω-deg−2 and is independent of temperature. The absolute Seebeck coefficient is very close to zero, its largest magnitude being −2.6 μV/°K and occurring at 450°K. Data are also presented on the Seebeck coefficient of tungsten up to 1400°K.This publication has 7 references indexed in Scilit:
