By combining X-ray diffraction and X-ray absorption spectroscopy, the structural evolution of the InSe alloy has been explored up to 3.3 GPa and 1500 K with the use of the Paris–Edinburgh large volume cell. These conditions allowed us to study the solid and the liquid states and to measure the pressure evolution of the melting point, which increases at a rate of +120 K GPa−1. A temperature‐induced phase transition has been evidenced within the solid phase. This is the first in-situ study of the high temperature solid phase which had so far only been inferred from studies on recovered samples at ambient conditions.
