摘要：

The structural stability in TaSi2 was investigated by in situ angle dispersive X-ray diffraction (AD-XRD), which shows that the structure is stable even up to about 50.0 GPa at room temperature. However, under high pressure and high temperature (HPHT) conditions it was revealed that TaSi2 could undergo a structural phase transition from a C40-type hexagonal phase to a metastable phase after a temperature quench from 573 K at 10.6 GPa.
