Abstract: At vacuum, the metal vanadium was heated to high temperature for long time in order to remove the gas absorbed on the metal surface. After several absorbing-releasing deuteride cicrles, vanadium can be activated and the absorbed deuteride is saturated, and the vanadium-deuteride ratio is 2.0. The activating conditions are as follows: 400 ℃ of the activating temperature, 4 h of the lasting time, 80-100 ℃ of the initial adsorbing temperature, purified deuterium or D-T gas, 2 or 3 cicrles of absorbing-releasing deuteride. Study of vanadium hydride performance was also peformed, and the parameters measured in experiment are as follows: 0.2 MPa of equilibrium pressure at 20 ℃ and 60 MPa of equilibrium pressure at 200 ℃, 0.47 L/g of absorption capacity, 6.1% of residual capacity. The prepared vanadium hydride gas resource by this method has been successful applied in ICF high-pressure filling experiment.
