Thermal expansion coefficients of NdBa2Cu3O7−δ
Physica C: Superconductivity, 1993Abstract For epitaxy of high- T c superconductor (HTSC) the knowledge of thermal expansion coefficients is very important to master cracking and strain problems. In this paper, the thermal expansion coefficients of NdBa 2 Cu 3 O 7− δ (0.15⩽δ⩽0.60) were measured by means of neutron diffraction in the temperature range from room temperature ...

Thermal expansion coefficient of 3C–SiC
Applied Physics Letters, 1995Theoretical results for the temperature dependence of the thermal expansion coefficient for 3C–SiC are reported using a phenomenological lattice dynamical theory in the quasiharmonic approximation. The linear thermal expansion coefficient α of 3C–SiC exhibits a variation with temperature much like that of the specific heat and, unlike other ...

The coefficient of thermal expansion of stroma
Experimental Eye Research, 1971Abstract Rabbit stroma has a negative coefficient of thermal expansion. Upon raising the temperature of a bare stroma, 200 μm thick, from 1–37°C while bathed in isotonic saline and loaded to 53 mmHg swelling pressure the thickness decreases about 14 μm. An increase in thickness of about the same amount can be observed upon cooling a bare stroma. This

Thermal Expansion Coefficient of KAP Crystals
Review of Scientific Instruments, 1973We have measured the coefficient of thermal expansion of potassium acid phthalate crystals in the direction perpendicular to the cleavage planes. This is the direction applicable to x-ray diffraction with interplanar spacings of 13.3 Å. The measured value is 40.5 × 10−6 °C−1 with an estimated uncertainty of about ± 5%.

Thermal Expansion Coefficient of Boron Monophosphide
Japanese Journal of Applied Physics, 1976Thermal expansion of BP epitaxially-grown on Si{111} and Si{100} substrates has been investigated by using a high-temperature X-ray diffractometer. The coefficient α varies from (4.0±0.3)×10-6 to (6.2±0.3)×10-6 K-1 in the tempeature range of 400–800 K. The unit-cell dimension of BP on Si{111} is about 0.1 % larger than that of BP on Si{100}.

Thermal expansion coefficient of alkali metals
physica status solidi (b), 1983AbstractThe thermal expansion of alkali metals is investigated using a local Heine‐Abarenkov model potential in the perturbational method. The mode Grüneisen parameters and the temperature‐dependence of both the mean Grüneisen constant and the thermal expansion coefficient are calculated, and the obtained results are quantitatively in good agreement ...

Thermal expansion coefficients of cracked laminates
Composites Science and Technology, 1988Abstract Effective thermal expansion coefficients of cross-ply laminates containing many intralaminar ply cracks are evaluated as functions of ply thermomechanical properties and crack density. The method employed is applicable to any cracked laminate if internal stress fields due to mechanical loads are known.

Thermal expansion coefficients of laminar composites
Polymer Mechanics, 1972The conclusion of [1], according to which the coefficient of linear expansion of a laminar composite in a direction orthogonal to the laminations may exceed the greater of the coefficients of linear expansion of the components, has been experimentally verified. The experiments were performed on laminated metal-plastics composed of alternating layers of

Thermal Expansion Coefficients of Manganese Fluoride
Physical Review, 1959The expansivity ($\frac{\ensuremath{\Delta}l}{{l}_{273.2}}$) and linear thermal expansion coefficient [${l}^{\ensuremath{-}1}{(\frac{\mathrm{dl}}{\mathrm{dT}})}_{p}$] have been measured for the $a$ and $c$ axes of manganese fluoride. There is a marked anomaly in the linear thermal expansion coefficients at the N\'eel temperature; the N\'eel temperature
