Mj. Assael et al., TOWARD STANDARD REFERENCE VALUES FOR THE THERMAL-CONDUCTIVITY OF HIGH-TEMPERATURE MELTS, International journal of thermophysics, 18(2), 1997, pp. 439-446
The paper describes the progress made in the development of an instrum
ent for the measurement of the thermal conductivity of molten material
s at high temperatures. The instrument is designed to provide experime
ntal data of unique accuracy at temperatures up to 1500 K on a wide ra
nge of materials, some of which will be suitable as standard reference
substances. In particular, the paper concentrates upon the method of
analysis of the experimental data and upon those critical aspects of t
he experimental technique which will enable a high accuracy to be achi
eved. Demonstrations of the validity of the method of treating one cor
rection and of its behavior under typical conditions are included.
