Available in PDF, EPUB and Kindle. Book excerpt: A compilation is presented of original test data on emittance, reflectance, and adsorptance of Cr, Nb, Mo, Ta, and W. The data were taken from the literature published during the period 1940-1959 inclusive, and as much of the 1960 literature as could be obtained. The following sources were searched: Chemical Abstracts, Ceramic Abstracts, Metallurgical Abstracts, Nuclear Science Abstracts, and the files of the Defense Metals Information Center (DMIC). An attempt was made to evaluate these sources of data according to the apparent thoroughness of methods and techniques as described by the various investigators. In many cases the descriptions in the literature are a summary of methods and results, and a complete evaluation is impossible. Curves are presented which appear to indicate the most probable values for the various conditions and materials. (Author).
