DETERMINATION OF THE THERMODYNAMIC PROPERTIES OF SEVERAL REFRACTORY COMPOUNDS. Quarterly Progress Report No. 1, May 1 to August 1, 1960

About 1,000 references on the thermodynamic properties of a limited number of refractory materials (oxides, carbides, nitrides, and borides of elements in groups IIA, IVB, VB, VIB, VIIB, plus Sc, Os, snd Si) were uncovered, and an author bibliography of 730 of these references is presented. Procedures for searching the literature and processing the data are described. Eighteen compounds for which there is little thermodynamic data available were obtained and/or prepared and analyzed, and equipment for enthaipy snd heat capacity determinations are discussed. Heat capacity data are presented for Ti nitride, Ta carbide, and Nb carbide at temperatures varying from 3031 to 4120 deg F. (D.L.C.)
