Abstract

Layered Ti<inf>3</inf>SiC<inf>2</inf> and Zr<inf>3</inf>[Al(Si)]<inf>4</inf>C<inf>6</inf> ceramics were prepared by hot-pressed sintering. The spectrally selective absorption properties of these layered carbides have been investigated and compared with those of TiC and ZrC. It is found that the Ti<inf>3</inf>SiC<inf>2</inf> ceramic exhibits a solar absorbance of 0.70 and a thermal emissivity of 0.19, yielding spectral selectivity (absorbance divide by emissivity) of 3.7, while the spectral selectivity of Zr<inf>3</inf>[Al(Si)]<inf>4</inf>C<inf>6</inf> is 2.8 (0.71/0.25). To evaluate the suitability of these ceramics as high-temperature absorbers for solar radiation, the investigation on the thermal stability and temperature dependent emittance was performed in air. Compared with TiC and ZrC, both Ti<inf>3</inf>SiC<inf>2</inf> and Zr<inf>3</inf>[Al(Si)]<inf>4</inf>C<inf>6</inf> show better thermal stability. Meanwhile, Ti<inf>3</inf>SiC<inf>2</inf> and Zr<inf>3</inf>[Al(Si)]<inf>4</inf>C<inf>6</inf> exhibit a low emissivity in the investigated temperature range, benefiting from their metal-like electrical conductivity.
