本発明はチタン系水素ｇ＆蔵用合金に関し、特に工業的

る水素＃＆蔵開用合金関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a titanium-based hydrogen g&storage alloy, particularly in the usage temperature range of 100 to 25, which can be used as industrial waste heat.
0'O, hydrogen pressure 1 to 10 atmospheres to form metal hydride alloys.
水素は資源的に制限がなくクリーンであること、輸送及
び貯蔵が容易である仁と等の理由から化石燃料に代る新
しいエネルギー源として注目されている。Hydrogen is attracting attention as a new energy source to replace fossil fuels because it is clean, has no resource limitations, and is easy to transport and store.
しかし、水素は常温で気体でありしかも液化温度が極め
て低いから、その貯蔵技術が重要となる。However, since hydrogen is a gas at room temperature and its liquefaction temperature is extremely low, storage technology is important.
この貯蔵法としては水素を金属に吸蔵させ金属水素化物

装置等への応用研究も進められている。One way to store this is to absorb hydrogen into a metal and store it as a metal hydride.These metal hydrides have been attracting attention recently because they can store hydrogen at a density that is almost the same as or higher than that of liquid hydrogen. are collecting. In addition, the hydrogen absorption/release reaction by metals is reversible, and a considerable amount of reaction heat is generated or absorbed during the reaction, and the hydrogen absorption/release pressure depends on temperature. Application research is also underway for heating and cooling equipment, thermal energy/pressure (mechanical) energy conversion equipment, etc.
従来から水素を多量に吸蔵し、金属水素化物を形成する
水素貯蔵用材料としてＯａ 、 Ｌｉ 、 Ｋ 。Oa, Li, and K have traditionally been used as hydrogen storage materials that absorb large amounts of hydrogen and form metal hydrides.

びその逆の分解放出反応を容易に行う。しかしなから、
実用化に際しては圧力・温度の制約を受けるので当然そ
の種類は限定される。These metals or alloys easily undergo a hydrogenation reaction in which hydrogen is stored, and a decomposition and release reaction in the opposite manner, under the appropriate hydrogen pressure and temperature relationship. However, because
When put into practical use, there are restrictions on pressure and temperature, so of course the types are limited.
たとえば工業的に多用される水素の圧力は約１〜１０気

囲に含まれる吸蔵用材料を選定する必要がある。もしこ
の選定をあやまれば平衡圧が異状に上昇したり又は常圧
以下に低下したりして、いずれも実用面や装置の安全性
の点で問題が多い。For example, the pressure of hydrogen, which is often used industrially, is about 1 to 10 atmospheres, so the hydrogen equilibrium pressure must be within this range and the temperature at equilibrium must be within the operating temperature range when the storage material is actually used. It is necessary to select the storage material. If this selection is incorrect, the equilibrium pressure may rise abnormally or fall below normal pressure, both of which pose many problems in terms of practicality and safety of the device.

。On the other hand, among conventional metal hydrides, Mg and Mg-based alloys are metals or alloys that are used in high-temperature regions and are known to have a very large hydrogen storage capacity. However, Kg
has the drawback that activation requires high temperature and high pressure, and it takes an extremely long time for hydride formation and hydrogen release from the hydride. Magnesium-nickel alloys and magnesium-copper alloys are alloys that have slightly improved the above-mentioned problems, but they still have problems such as difficulty in activation and slow hydrogen storage and release rates, which have not yet been completely improved. This has not yet been achieved.
