Linear Thermal Expansion of Aluminum Oxide and Thorium

The linear thermal expansion of single‐crystal and polycrystalline aluminum oxide and poly‐crystalline thorium oxide was measured from 100° to 1100° K with an interferometric technique. For each substance the results are well described by Gruneisen''s equation using a Nernst‐Linde‐mann energy function.
