Сравнительные исследования ампул реперной точки плавления эвтектики кобальт – углерод, созданных во ВНИИМ и ВНИИОФИ
Abstract
Two Russian national metrological institutes – VNIIM and VNIIOFI – independently designed and created the high-temperature fixed point blackbody cells of the cobalt – carbon eutectic (1324 ºС). A comparison of the developed Co-C cells was carried out for determination a probable difference in the cells melting temperatures. Radiance-mode radiation thermometers with central wavelength of about 650 nm were used for the fixed-point melting temperature measurements. This article presents the comparison details and its preliminary results and shows the concidence between melting temperatures of the compared cells within 20 mK limits.
