Thermal expansion of cancrinite
I n t r o d u c t i o n THE structures of the cancrinite-group minerals are character ized by parallel s ix-membered rings consisting of alternating A104 and SiO4 tetrahedra. The hexagonal symmetry is the result of the stacking of such six-membered rings in an AB... sequence. This stacking leads to large continuous channels that are formed by twelve-membered rings of alternating A1Oa and SiO4 t...
متن کاملThermal stability of a-titanium in contact with titanium nitride
The thermal stability of an a-Ti film in contact with a d-TiN film in the structure of a TiN/Ti/TiN film stack on SiO2 substrates was studied by in situ sheet resistance (Rs) measurement, Auger electron spectroscopy, glancing angle x-ray diffractometry, cross-sectional transmission electron microscopy, scanning electron microscopy, and atomic force microscopy. It was found that nitrogen dissolv...
متن کاملFundamentals of Thermal Expansion and Thermal Contraction
Thermal expansion is an important property of substances. Its theoretical prediction has been challenging, particularly in cases the volume decreases with temperature, i.e., thermal contraction or negative thermal expansion at high temperatures. In this paper, a new theory recently developed by the authors has been reviewed and further examined in the framework of fundamental thermodynamics and...
متن کاملFiber - Optic Sensing of Linear Thermal Expansion (RESEARCH NOTES)
The use of a LED fiber-optic sensor to measure displacement and linear thermal expansion is described. It has a sensitivity of about 0.6 mV/mm, a resolution of 1.25 mm, and a dynamic rang of 400 mm for displacement measurements. For thermal expansion, it shows a sensitivity of about 3.5 mV/C, and the experimental linear expansion values are in agreement with those calculated. The reported senso...
