Abstract
In the structural map for dialuminides based on Miedema parameters, the compound ThAl2, which crystallizes in the AlB2 structure at ambient conditions, falls in the region of Laves phase (MgCu2) compounds. Using four probe electrical resistance and Be gasketed X-ray diffraction measurements, we have shown that only moderate pressure (≈ 0.3 GPa) is required to transform it to the structure predicted by the structural map.
