Abstract : The work includes a study of the thermodynamics of the borides, carbides, nitrides, and oxides of 31 elements in the temperature range from 0 to 6000K. The elements are (a) group IIA--beryllium, magnesium, calcium, and strontium; (b) group IIIB--scandium, yttrium, and lanthanum, (c) group IVA--silicon; (d) group IVB--titanium, zirconium, and hafnium, (e) group VB--vanadium, niobium, and tantalum; (f) group VIB--chromium, molybdenum, and tungsten; (g) group VIIB--manganese, technetium, and rhenium; (h) group VIII--rhodium, osmium, iridium, and platinum; (i) rare earths--cerium, neodymium, samarium, gadolinium, and dysprosium; and (j) actinides--uranium and thorium. More than 160 thermodynamic tables, together with comprehensive discussions, were prepared. Volume 1, presents a summary of the techniques used to analyze thermodynamic data and gives the data analyses for refractories considered.
