Study the change of some physical and chemical properties of TiN under high pressure

The pressure equation of state of Titanium nitrate TiN was investigated in the current work using two equations of state (EOS) from the literature, including the Barden EOS and the Birch-Murnaghan EOS, whereas the Bardeen EOS, which is based on interstellar atomic potentials, and the Birch-Murnaghan EOS, which is based on the solid mechanics notion of finite strain. The EOSs were processed to identify the impacts of high pressure on the bulk modulus B, Debye temperature θD and lattice constant a, which are characterizations of TiN. Ultimately, a fair comparison of the current findings with the first principle approximation and the generalized gradient approximation approach was conducted, and a perfect agreement was found. It was demonstrated that TiN EOS can be used to calibrate high pressure for chemical compound TiN .
