CARBONIZATION OF PLASTICS AND REFRACTORY MATERIAL RESEARCH. VOLUME 2. REFRACTORY MATERIALS
Abstract
Vapor pressure studies were conducted through the application of Langmuir evaporation, Knudsen effusion, matrix isolation and resonance line absorption techniques. The vaporization of hafnium and zirconium nitrides was studied by the Knudsen effusion method; the Langmuir evaporation method was applied to pure hafnium metal. Matrix isolation of vapor over thoria proved successful and structural assignments were made to various bands in the infrared absorption spectra of the matrix isolated species. Resonance line absorption photometry studies of TiB2 were completed. Normal spectral emissivity data from 0.4 to 5.0 microns and from 1500 to 2500 K, supported by systematic methods of material characterization, were obtained for the compounds niobium diboride, zirconium diboride, titanium diboride, tantalum nitride, hafnium nitride, and zirconium nitride.
