Temperature dependence of (a) Si cell parameter [open diamonds derived from experimental dilatometry data; solid line from equation (3)] and (b) Al2O3 cell parameters (solid lines) used in this work. (c) The difference in thermal expansion, here plotted as V(T)/V(293.15 K), allows a direct measure of temperature.
