“…ZrB 2 and TaB 2 ), while the spectral selectivity α/ε is higher than that of SiC and lower than ZrB 2 and TaB 2 [7]. In the temperature range of 1100-1200 K, the thermal expansion coefficient is the closest in LaB 6 and TiB 2 phase components of the composite in comparison with other diborides [10], which ensures the compatibility of deformation of the phase components of the LaB 6 -TiB 2 composite and is a significant advantage for its application.…”

The structure and properties of bulk and powder LaB 6 -TiB 2 composites as a promising material in solar energy converters have been studied by X-ray, metallographic, and pulsed excitation methods. The phase composition and defects of the composite's structure have been determined. The effect of heating-cooling cycles (20-1400°C) on the structure's characteristics of the composite's matrix phase is shown. The compatibility of the structure's analysis results by destructive (X-ray and metallographic) and nondestructive methods (pulsed excitation have been established). The capabilities of the pulsed excitation method for determining the composites structural characteristics and using it to control their quality under operating conditions are demonstrated.
