Application of metal (carbide)?carbon eutectic fixed points in radiometry
Metal (carbide)–carbon eutectic fixed points when applied to radiometry should operate at a temperature preferably exceeding 3000 K, have a large aperture, be robust and have long plateau duration.Expand

Thermodynamic temperature determinations of Co–C, Pd–C, Pt–C and Ru–C eutectic fixed-point cells
Thermodynamic temperatures during the melt and the freeze of Co?C, Pd?C, Pt?C and Ru?C metal?carbon fixed-point cells manufactured by LNE?INM/CNAM, NMIJ and NPL were determined by absolutelyExpand

A Study on the Feasibility of Measuring the Emissivity with the Laser-Flash Method
The laser-flash method is a fast, widely used and well established technique to measure the thermal diffusivity. Since its introduction in the 1960s, it was proposed to expand this technique to theExpand

Investigation of Furnace Uniformity and its Effect on High-Temperature Fixed-Point Performance
A large-area furnace BB3500YY was designed and built at the VNIIOFI as a furnace for high-temperature metal (carbide)–carbon (M(C)–C) eutectic fixed points and was then investigated at the NMIJ. TheExpand

Thermal Effects in the HTBB-3200pg Furnace on Metal-Carbon Eutectic Point Implementation
The general statement that a temperature fixed-point cell will show better melting and freezing plateaux with better temperature uniformity along the dimensions of the fixed point is understood to beExpand

Comparison of the Richardson–Lucy method and a classical approach for spectrometer bandpass correction
Bandpass correction in spectrometer measurements using monochromators is often necessary in order to obtain accurate measurement results. The classical approach of spectrometer bandpass correction isExpand

Thermodynamic temperature assignment to the point of inflection of the melting curve of high-temperature fixed points
The thermodynamic temperature of the point of inflection of the melting transition of Re-C, Pt-C and Co-C eutectics has been determined to be 2747.84 ± 0.35 K, 2011.43 ± 0.18 K and 1597.39 ± 0.13 K,Expand
