Abstract
A ternary intermetallic compound having the formula Zr(V.sub.1-x Cr.sub.x).sub.2 where x is in the range of 0.01 to 0.90 is capable of reversibly sorbing hydrogen at temperatures ranging from room temperature to 200.degree. C., at pressures down to 10.sup.-6 Torr. The compound is suitable for use as a hydrogen getter in low pressure, high temperature applications such as magnetic confinement fusion devices.
Claims4
In a method of gettering hydrogen from a low pressure environment comprising contacting the hydrogen at a pressure as low as 10.sup.-6 torr with a ternary intermetallic compound, the improvement wherein said compound has the formula Zr(V.sub.1-x Cr.sub.x).sub.2 where 0.01.ltoreq.x.ltoreq.0.90, and wherein x is preselected in accordance with the requirements of said gettering environment such that when x is low, the minimum hydrogen gettering pressure is lower and the gettering temperature is higher, and when x is high, the minimum hydrogen gettering pressure is higher and the gettering temperature is lower.
