Thermal expansion of solid argon from 1 to 25 K

A method is described by which the equation of state of liquids and reasonably soft solids can be determined experimentally. A unique feature of the apparatus is that while the quantity of material occupying a known volume is weighed, pressure and temperature are measured concurrently. First results are reported for solid and liquid argon in the temperature range from 96 to 154 °K and at pressures from about 100 to 2000 kg/cm2. The liquid data determine the PVT surface to within 0.1% for each of the variables. Data for solid argon have so far been limited to a zone of 20-degree width along the melting line. Thermal expansion and compressibility of the liquid are computed. From the volume change on melting it is concluded that the latent heat increases linearly over the full pressure range.

Solid Argon

A linear chain model of a close-packed line of atoms in a solid has been constructed. The model differs from usual linear chain models in that the chain is not strictly one-dimensional, the individual atoms being free to move in three dimensions. To account for the interaction of the chain with its surroundings an effective potential has been introduced. When the thermal expansion of solid argon is calculated, satisfactory agreement with experiment is obtained in the classical region.

Solid Argon

A series expansion in powers of Planck's constant is adapted to yield the quantum mechanical correction to the classical statistics of an "almost one�dimensional" system. The result is of validity at the high temperature end only of the specifically quantum temperature region. Application to the thermal expansion of solid argon gives reasonable agreement with experiment.

Microchemical Characterization

Nickel sulfide inclusions have been implicated in the spontaneous fracture of large windows of tempered plate glass. Two alternative explanations for the fracture-initiating behaviour of these inclusions have been proposed: (1) the volume increase which accompanies the α to β phase transformation in stoichiometric NiS, and (2) the thermal expansion mismatch between the nickel sulfide phases and the glass matrix. The microstructure and microchemistry of the small inclusions (80 to 250 μm spheres), needed to determine the cause of fracture, have not been well characterized hitherto. The aim of this communication is to report a detailed TEM and EDS study of the inclusions.
