One, material of hydrogen of rare earth lay aside

  people early discovers, rare-earth metal and hydric reaction generate REH of rare earth hydride₂, this kind of hydride heats to just can be decomposed to 1000 ℃ above. And join in rare-earth metal certain after the 2nd kind of metal forms alloy, also can suck below inferior temperature put hydric, call this kind of alloy alloy of lay aside hydrogen normally. In material of a series of lay aside hydrogen that already developed, function of material of hydrogen of store of rare earth department is optimal, application is most wide also. Its apply a domain to already enlarged the sources of energy, chemical industry, electron, space navigation, military affairs to reach civil each respects. The alloy of hydrogen of rare earth lay aside that is used at chemical accumulation of heat and chemical heat pump is OK reclaim the low qualitative heat energy such as the useless heat of the factory, warm up, thereby the new way that open up gave the mankind to use all sorts of the sources of energy effectively. Use material of hydrogen of rare earth lay aside to release hydric when the pressure of generation, can use as the motivation of hot drive, use alloy of hydrogen of rare earth lay aside to be able to realize bulk small, weight power of light, output is great, can use at brake spiral lifting device and temperature sensor.

  oil and coal are the mankind fuel of two great main energy resources, but because their reserves is limited, the problem such as environmental pollution produces in use process, because this solves the sources of energy,shortage and environmental pollution make one of focal points that study now. Hydrogen is the material of ideal the sources of energy of a kind of complete free from contamination, have benzine of prep above of unit quality quantity of heat the high energy density of double above, can extract from inside water. The key that hydrogenous energy development uses depends on whether economic ground production and high density safety are made take and hydrogen of lay aside carry.

The LaNi of alloy of lay aside hydrogen of   model₅Was 1969 company of riverside of Holand humble benefit discovers, caused people to fasten the research of Chu Qing material to rare earth thereby.

1. Hydric keep in storage and extract

Alloy of hydrogen of store of department of   rare earth is OK store is much hydric. With before high-pressured bottle photograph is compared, the weight of container of alloy of lay aside hydrogen is basic and identical, but bulk can narrow 1/4, can leave store in low-pressure force, and unless exterior heat, won't give off otherwise hydric. Accordingly, hydrogen of keep in storage of alloy of the hydrogen that use store on the safe side.
