11. When the system is cooled, even more mismatch is introduced from the mismatch in thermal expansion coefficients . 12. Where is the mass concentration at a reference temperature, is the thermal expansion coefficient of the mixture. 13. The dislocations are introduced during cooling by the SiC particles, due to their different thermal expansion coefficient . 14. It is refractory with a melting point of 2430 �C and has a moderate coefficient of thermal expansion coefficient . 15. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient, and the most relevant for fluids. 16. The volumetric thermal expansion coefficient is the most basic thermal expansion coefficient , and the most relevant for fluids. 17. Therefore the sign of thermal expansion coefficient is determined by the sign of the third derivative of the potential. 18. :: : There are a number of materials that have a negative thermal expansion coefficient over a temperature range. 19. The gridiron pendulum consists of alternating parallel rods of two metals with different thermal expansion coefficients , such as steel and brass. 20. Such materials are often used as substrates for chips, as their thermal expansion coefficient can be matched to ceramics and semiconductors.
