thermal expansion coefficients for SiC this material was the initial motivation for adding fourth order polynomials, but I could not find a reliable source for the graphs send to damask@mpie.de. It seems that the CTE levels off for even higher temperature which calls for a higher order polynomial 2023-01-08 16:30:55 +05:30			`type: thermalexpansion`
