The research work presented in this paper shows influence of filler composition in inorganic composite on its emissivity. Chromium Oxide is an active ingredient, which is present in the basic formula of BG HitCoat®. Also other active ingredients (Iron powder, Kaolin, Silicon Carbide, Boron Carbide, Boron Nitride and Aluminum Nitride) were built in the matrix of the composite. Thermal stability up to 900 °C was analyzed. Spectral dependence of emissivity for different temperatures was measured by FTIR spectrometer for each sample. These tests demonstrated that filler composition is able to influence emissive properties in the range of short IR wavelength (1.5–4.0 μm) within 0.7–1.5 times (against the reference).
▶ Several active ingredients (with high emissivity) are built-in into matrix of the ceramic composite. ▶ The samples are subjected to analysis using SEM and XRD. ▶ FTIR spectrometer can measure the emissivity in the temperature range of 400–1200 °C and at wavelengths of 1.0–28.5 μm. ▶ Active ingredients can influence emissive properties.
