摘要：

We have investigated the structural and dehydriding properties of Ca(BH4)(2). It was found that Ca(BH4)(2) undergoes a structural phase transformation from an orthorhombic low-temperature (LT) modification into a tetragonal high-temperature (HT) modification between 433 K and 523 K. The amount of hydrogen desorbed from Ca(BH4)(2) during the pressure-composition (p-c) isotherm measurement was 5.9 mass%. This hydrogen desorption is caused by the partial dehydrogenation of Ca(BH4)(2) accompanied by the formation of CaH2 and orthorhombic intermediate phases.
