Multispectral High Temperature Thermography [PDF]

Sensors, 2022
The paper considers the issues of creating high-temperature digital thermographs based on RGB photodetector arrays. It has been shown that increasing the reliability of temperature measurement of bodies with unknown spectral coefficient of thermal radiation can be ensured by optimal selection of the used spectral range and registration of the observed ...

Electrical Conductivity of Thin Film SrTi_0.8Fe_0.2O_3−δ-Supported Sr_0.98Zr_0.95Y_0.05O_3−δ Electrolyte

Ceramics, 2022
Thin films of Sr0.98Zr0.95Y0.05O3−δ (SZY) electrolyte were grown on porous supporting SrTi0.8Fe0.2O3−δ electrodes by the chemical solution deposition method from a low-viscous solution of inorganic salts. The films were characterized by X-ray diffraction

Thermal properties of fluoride mixtures near the melting point

Chimica Techno Acta
The thermal diffusivity of LiF-NaF-KF (FLiNaK), NaF-KF and FliNaK-NdF3 mixtures was studied by laser flash method near the melting point. The obtained results demonstrate that the thermal diffusivity of the melts slowly decreases within a certain ...
