用化学方法合成了结晶良好的Mg(BH4)(2)，考察了球磨和钛基添加剂对其脱水性能的影响。合成的Mg(BH4)(2)的脱氢反应在K附近开始，大约13.7%的氢被脱附。与合成的Mg(BH4)(2)相比，球磨后的样品变化不大，而添加TiCl3显著降低了Mg(BH4)(2)的初始脱水温度，即从K降至361K。(C)2007由Elsevier Ltd.出版的材料学报。版权所有。
Well-crystallized Mg(BH4)(2) was chemically synthesized and the effect of ball milling and Ti-based additives on the dehydriding properties were investigated. The dehydriding reaction of the as-synthesized Mg(BH4)(2) initiates at approximately 535 K and about 13.7 mass% of hydrogen is desorbed. Compared with the as-synthesized Mg(BH4)(2), few changes are observed in the samples after ball milling, while the initial dehydriding temperature of Mg(BH4)(2) is significantly reduced by the addition of TiCl3, i.e. from 535 K down to 361 K.
