An approximate theoretical treatment of the narrow sandwich seal provides the necessary correction factor for calculating true thermal expansion mismatch between seal members from the observed birefringence. The shape factor, which physically represe

Thermal expansion data are presented for two glasses for both heating and cooling at constant rates. Heating data were taken on samples with varying thermal histories brought about by either constant-rate cooling or by constant-temperature stabilizat

A novel Priest-type interferometer has been built to measure small differences in expansion of fused silica. The interferometer block consists of a 3-cm. diameter cylinder, 10 cm in height, wrung onto a shorter cylinder. The sample is supported in a

In this paper we examine the effect of the seal length on the magnitude of residual stresses and the expansion differential derived from them. Two potential errors can arise which, if uncorrected, can lead to substantially lower values of expansion d

Macroscopic and x‐ray volume expansivity measurements have, in recent years, yielded information about the formation energies and entropies of atomic vacancies in several crystalline solids. Such vacancy data may now be utilized in conjunction with

X‐ray diffraction data from high purity platinum, cold‐rolled to 0.13‐mm thickness, gives linear thermal expansion values in very good agreement with the optical comparator data of Austin and of Kirby and Rothrock. The intrinsically high reliab

The anisotropic compressibility behavior of hexagonal Selenium has been determined by high pressure x‐ray diffraction and also by high pressure neutron (time‐of‐flight) methods up to 52 kbars. The coefficients are: a‐axis 31.9 ± 7, c‐axis

To date, most applications of materials having very low thermal expansion have been near 20°C. In 1968 Plummer and Hagy reported measurements on some low‐expansion materials using Fizeau interferometry attaining high precision and accuracy. These
