Whereas titanium is a getter material mainly suitable for the long-term storage of tritium, zirconium cobalt alloy can also be employed for the interim storage and transport of this gas. Activated zirconium cobalt alloy reacts within minutes with hydrogen at room temperature. At the composition of ZrCoH0.8 the dissociation pressure at room temperature is estimated to be 10−3 Pa. The zirconium cobalt / H2 system is not pyrophoric at room temperature. Methane is partially cracked on Ti and on ZrCo at temperatures above 600 and 300°C respectively. With titanium the corresponding carbide is formed without affecting the storage properties of the getter. After reaction of ZrCo with CH4 or N2 the hydrogen absorption capacity is reduced. Titanium powder, sponge or sheet react with nitrogen at temperatures above 750°C with a parabolic rate law. In the overlayer of the metal substrate the phases N dissolved in α-Ti, Ti2N and TiN were identified. The same phases were observed when NH3 reacts with this metal.
