Intrinsic spectral selectivity in ultra-high temperature ceramics for solar applications

, 2011
Different concepts for solar receiver systems have been developed, and each collector architecture (linear parabolic systems, solar dishes, solar tower plants, etc) demands peculiar system solutions.

Ultrahigh-Temperature Ceramics (UHTCs) Systems

2018
Phase diagrams of diborides (MB2), monocarbides (MC), and mononitrides (MN) of transitive metals in IVB or VB groups, such as Ti, Zr, Hf, Nb, and Ta, most of which belong to the Ultrahigh-Temperature Ceramic (UHTC) family, are collected in this chapter. Phase diagrams of UHTCs are scarce relative to common oxides, carbides, or nitrides.

Predicting Mechanical Properties of Ultrahigh Temperature Ceramics Using Machine Learning

Journal of the American Ceramic Society, 2022
Ultrahigh temperature ceramics (UHTCs) have melting points above 3000°C and outstanding strength at high temperatures, thus making them apposite structural materials for high-temperature applications.

Single-Source-Precursor Synthesis of Hafnium-Containing Ultrahigh-Temperature Ceramic Nanocomposites (UHTC-NCs)

Inorganic Chemistry, 2014
Amorphous SiHfBCN ceramics were prepared from a commercial polysilazane (HTT 1800, AZ-EM), which was modified upon reactions with Hf(NEt2)4 and BH3·SMe2, and subsequently cross-linked and pyrolyzed. The prepared materials were investigated with respect to their chemical and phase composition, by means of spectroscopy techniques (Fourier transform ...

Polymer Precursor-Derived HfC–SiC Ultrahigh-Temperature Ceramic Nanocomposites

Journal of the American Ceramic Society, 2018
Due to poor mechanical properties and antioxidation properties, etc of single phase ultrahigh-temperature ceramics (UHTCs), the second phase such as SiC was usually introduced for improving those properties.
