Thermodynamics of Chemical Species Important to Rocket Technology.
Abstract
Using a subsecond-duration transient technique the specific heat, electrical resistivity, and hemispherical total emittance were simultaneously measured over the temperature range 1500-3000 K for some grades of graphite. Similar measurements were made on vanadium, and zirconium in the temperature range of 1500-2100 K. Melting points and radiance temperature (at 650 nm) are reported for zirconium and molybdenum. The temperature of the transition from the alpha-beta phase of zirconium and the energy difference of these phases has also been measured using the subsecond duration transient technique. The products of the reaction of Fe(g) and Ox have been investigated. A preliminary report on the study of the reaction of Ba(g) with vibrationally excited ozone is also presented. The dissociation energies of the scandium group and rare-earth gaseous monoxides are evaluated by reviewing the literature available on Knudsen effusion rates and mass-spectrometric data. A bibliography of the available literature on the spectroscopy of fluorides, oxides, and oxyfluorides belonging to the lanthanide series is given.
