Equations of state and electrical properties in TiH 2 and ZrH 2 at high pressure

Hydride has a very wide field. Properties of hydrides have been much studied at atmospheric pressure, and hydrides have been extensively applied in research and production. However, their properties at high pressure have been less studied. In recent years, there has been considerable interest in studying properties and metallic transitions of hydrides at high pressure. Straaten et al.have studied the properties of HI at high pressure and discovered an insulator-to-metal transition in HI at pressures of 42.5-51
