Discontinuous Thermal Expansions and Phase Transformations in Crystals at Higher Temperatures

Description: The purpose of this investigation is to make more detailed studies of transformations. Fourteen compounds have been examined by high temperature X-ray diffraction for this purpose. The investigations have been carried out in such a way as to reveal: 1. the existence of transformations, 2. the influence of polarizability on thermal expansion, 3. the anisotropy of expansion, and 4. the discontinuity of thermal expansion.

The Thermal Expansion of NaCl at High Pressures and Temperatures

Description: Abstract: The thermal expansion of NaCl at high pressures and temperatures is estimated by extrapolating high temperature compressibility data to high pressures using finite strain theory. The thermal expansion is apparently negative at pressures over 50,000 bars at 300°C and at higher pressures at other temperatures.

Thermal relations for two-phase expansion with phase equilibrium and example for combustion products of boron-containing fuel

Description: Report presenting a procedure for integrating equations involving pressure, temperature, and density in order to analyze an expansion process that occurs when boric oxide from fuels condenses during expansion. An example is provided to illustrate the manner in which the equations can be used to analyze a one-dimensional expansion with phase equilibrium.
