In this work, we present normal spectral emissivity data of solid and liquid molybdenum at a wavelength of 684.5 nm. The presented results are novel measurements on molybdenum, a material, which was already measured 15 years ago by our group. The present results indicate a lower emissivity in the liquid phase. The novel measurements were done within the European Metrology Programme for Innovation and Research (EMPIR) project 17IND11 Hi-TRACE. The optimized measuring system is an ohmic pulse-heating apparatus combined with microsecond Division of Amplitude polarimetry.

固态和液态钼在684.5 nm处的正光谱发射率的重新研究

在这项工作中,我们展示了固态和液态钼在684.5 nm波长处的正常光谱发射率数据。提出的结果是对钼的新颖测量,钼是我们小组15年前就已经测量的。目前的结果表明液相的发射率较低。在欧洲计量学创新和研究计划(EMPIR)项目17IND11 Hi-TRACE中完成了新颖的测量。优化的测量系统是欧姆脉冲加热设备,结合了微秒的振幅极化测量法。
