Conclusions

An analysis of published data has shown that refractory compounds can be regarded as potentially useful materials for direct energy conversion devices. Further work would appear to be desirable in the following directions: 1) development of polycrystalline materials of increased purity (for example, pyrolytic coatings) whose adsorption properties could be regulated by varying their composition and hence the spectrum of chemisorption binding; 2) synthesis of single crystals, which may open up wide possibilities for the selection of faces with optimum emission-adsorption characteristics. The existence of such a choice is due to a pronounced anisotropy of properties, brought about by the strongly heterodesmic atomic interactions in single crystals of refractory compounds — a result of the presence of metal- nonmetal and nonmetal-nonmetal bonds as well as of metal-metal interactions.
