Abstract
A kind of hydrogen-storage alloy adopts special design proportioning, is base with titanium, iron, adds the 3rd dvielement Cr, makes it to form TiFe
xCr
yThe hydrogen-storage alloy of system, its hydrogen desorption capacity can reach 241.71/kg, and advantage such as it is good, cheap to have an activation performance, of many uses.
Description
The invention belongs to the field of metallurgy of hydrogen-storage alloy.
State such as the U.S., Holland is since the sixties, and just the someone utilizes the characteristics that compound can reversibly be inhaled amplification quantity hydrogen between some series metal, the Ti-Fe hydrogen-storage alloy is studied, but Ti-Fe alloy activation difficulty.Later on again the someone studied in the Ti-Fe alloy add the 3rd, quaternary usually improves its activation performance, but reduced its hydrogen storage capacity.Therefore it is big to study hydrogen storage capacity, and activation is easy to the problem that new alloy has become people to be concerned about again.The most close with the present invention is nineteen eighty-three No. 4370163, United States Patent (USP), the Tii-xAxFey-zBz hydrogen-storage alloy, wherein A represents Zr, Hf or their mixture, x=0.01～0.1; B represents transition element Cr, Cu, Co, Mo, V, Ni, Nb, Mn and their mixture, and these alloys have improved the speed for hydrogen absorbing and releasing of Ti-Fe alloy, and hydrogen storage capacity is preferably arranged, but its highest Hydrogen Energy power of putting is when only reaching 206l/kg(20 ℃).From present Ti-Fe base hydrogen-storing alloy both domestic and external, except that the activation performance of some alloy made moderate progress, hydrogen desorption capacity all failed to surpass this level, but the Tii-xAxFey-zBz hydrogen-storage alloy contains expensive rare metals such as Zr, Hf, thereby cost is higher.
The present invention is the method that adopts CALCULATING PREDICTION, designed effectively with the Tii-xAxFey-zBz hydrogen-storage alloy of United States Patent (USP) and compared hydrogen-storage alloy with higher hydrogen desorption capacity, and do not contain rare metals such as Zr, Hf in the composition, so cost is significantly less than the Tii-xAxFey-zBz hydrogen-storage alloy.
The present invention is to be base with titanium, iron, adds the 3rd dvielement chromium, forms the TiFexCry series hydrogen storage alloy, and its composition is TiFexCry, wherein: x=0.7～1, x=0.875 is worked as in y=0.01～0.3, and during y=0.065, its hydrogen desorption capacity reaches as high as 241.7l/kg.
Advantages such as it is big that this hydrogen-storage alloy has a hydrogen desorption capacity, and activation performance is good and cheap, and is of many uses now have been used for hydrogen storage bottle, can prepare purity and be 6 nine ultra-pure hydrogen.
