Fine ceramics (advanced ceramics, advanced technical ceramics) — Measurement method for normal spectral emissivity using blackbody reference with an FTIR spectrometer
Preview
Summary
This document specifies a method used for the determination of normal spectral emissivity and normal
quasi-total emissivity of fine ceramics using blackbody reference with a Fourier transform infrared
spectrometer (FTIR) at elevated temperatures. This method is applicable to fine ceramics, ceramic
matrix composites, and continuous fibre-reinforced ceramic matrix composites which are opaque and
highly non-reflective at wavelengths between 1,67 µm and 25 µm. The applicable temperature range is
approximately 350 K to 1 100 K.
