Abstract

Taking account of the spectral radiation characteristics of materials in national defense, aerospace and other application areas, especially above 2000°C, we established a new ultra-high temperature spectral emissivity measurement system. The system covers 100∼2400°C temperature range and 2 ∼ 25μm spectral range with background radiation compensation and gas control function. Fourier transform infrared (FTIR) spectroscopy collects spectrum signal with DTGS detector. We have tested the system non-linearity response, spectral response function and optical path consistency, and evaluated blackbody's effective emissivity. In order to objectively evaluate results of measurement system, we measured spectral emissivity of graphite and ultra-high temperature ceramic material ZrB2-SiC, compared the results with literature's data and the agreement is obtained. Analyzed the factors that effects emissivity measurement results, the standard uncertainty of spectral emissivity at 10μ;m is less than 3%.
