It is pointed out that the thermal expansion coefficient of solids is not always zero even in ideally harmonic crystals, if one quantizes the phonon field. This apparently differs from the customary treatment which is essentially based on non-quantized phonon field model. Our discussion which starts
We have measured the temperature dependence of the cell parameter of cubic fl-cristobalite up to 1300 ~ C by high-precision X-ray powder diffraction. The thermal expansion coefficient decreases on heating, until above 1000 ~ C the cell parameter is virtually constant in value. We discuss this change
