Thermal expansion data

This paper gives regression data for a modified second order polynomial lifted to the expansion data of, and percentage expansions for sesquioxides with (a) the corundum structure: Al2O3, Cr2O3, Fe2O3, Ga2O3, Rh2O3, Ti2O3, and V2O3, (b) the A-M2O3 structure: La2O3, Nd2O3 and Pr2O3, and (c) the C-M2O3 structure: Dy2O3, Er2O3, Eu2O3, Gd2O3, Ho2O3, In2O3, Lu2O3, Mn2O3, Nd2O3, Pr2O3, Sc2O3, Sm2O3, Tb2O3, Tm2O3, Y2O3 and Yb2O3. The expansion curves for several of the corundum structures were complicated by the changes accompanying electrical or magnetic transitions. The 'law of corresponding states' appears to apply to the lanthanide sesquioxides with the A- and C-M2O3 structures. (author)
