主要介绍了一种新的非蒸散型大吸气量吸气材料。该材料由金属锆及其金属间化合物Zr Al16和Zr V Fe经真空烧结制成。通过吸气性能测试装置、X射线、扫描电镜等测试手段对材料吸氢性能及显微结构进行了分析。结果表明该材料具有比同类代表产品更优异的吸氢性能 ,并且在低温和高温条件下都具有好的吸氢能力。在 5 0 0℃低温激活第 10min吸气速率S10 达到 5 136 .5ml·s-1·g-1,特征吸气量Q10 达到 1835 14ml·Pa·g-1;80 0℃高温激活 10minS10 达到ml·s- 1·g-1,Q10 达到 2 2 4 936ml·Pa·g-1。
Mainly introduces a new non-evaporable large suction inspiratory material. The material is made of metal zirconium and its intermetallic compounds Zr Al16 and Zr V Fe by vacuum sintering. The hydrogen absorption properties and microstructure of the material were analyzed by means of inhalation performance test, X-ray and scanning electron microscope. The results show that the material has more excellent hydrogen absorption properties than the representative products, and has good hydrogen absorption capacity under the conditions of low temperature and high temperature. The inhalation rate S10 reached 5 136.5 ml · s-1 · g-1 at 10 min after low-temperature activation at 500 ℃ and the specific inspiratory capacity Q10 reached 1835 14 ml · Pa · g -1; · S-1 · g-1 and Q10 reached 2 24936 ml · Pa · g-1.
