Abstract
High pressure X-ray diffraction experiments were performed on ThAl2 up to 20 GPa. The results do not confirm the structural transition that had been reported in the literature, to have occurred at a very low pr essure of 0.3 GPa. It is observed that this system undergoes an isostr uctural transition around 5.5 GPa and a structural transition around 1 2 GPa. High pressure phase is found to adopt orthorhombic structure an d is stable upto 20 GPa.
