Claims
- 1. Method for the stoichiometric sorption of both oxygen and hydrogen from water which consists of contacting water with a non-evaporable ternary gettering alloy of Zr--Ti--Fe.
- 2. Method according to claim 1, in which the ternary alloy used comprises:
- from 45 to 75% by weight Zr
- from 5 to 20% by weight Ti and
- from 5 to 35% by weight Fe.
- 3. A method according to claim 1 in which the ternary gettering alloy comprising Zr, Ti and Fe having a composition which when plotted on a ternary composition diagram in weight percent Zr, weight percent Ti and weight percent Fe lies within a polygon having as its corners the points defined by:
- (a) 75% Zr--5% Ti--20% Fe
- (b) 60% Zr--5% Ti--35% Fe
- (c) 45% Zr--20% Ti--35% Fe
- (d) 75% Zr--20% Ti--5% Fe
- 4. Method according to claim 1, in which the water pressure is less than 100 Torr, the gettering alloy has a temperature between 200.degree. C. and 350.degree. C. and is able to sorb up to 4% by weight of water, and in which the particles of the gettering alloy have a particle size between 25.mu. and 125.mu..
- 5. Method according to claim 1 in which water is present in the form of water vapour.
- 6. Method according to claim 5 in which the water vapour is mixed with a rare gas.
- 7. Method for the stoichiometric sorption of both oxygen and hydrogen from water which consists of contacting water with a non-evaporable ternary gettering alloy comprising Zr, Ti, and Fe having a composition which when plotted on a ternary composition diagram in weight percent Zr, weight percent Ti and weight percent Fe lies within a polygon having as its corners the points defined by:
- (a) 75% Zr--5% Ti--20% Fe
- (b) 60% Zr--5% Ti--35% Fe
- (c) 45% Zr--20% Ti--35% Fe
- (d) 75% Zr--20% Ti--5% Fe;
- wherein, the water pressure is less than 100 Torr; wherein, the gettering alloy has a temperature between 200.degree. C. and 350.degree. C. and is able to sorb up to 4% by weight of water; and
- wherein particles of the gettering alloy have a particle size between 25.mu.and 125.mu..
