“…According to DFT calculations at 0 K the β phase has the lowest energy at atmospheric pressures, and it transitions to the α and α structures at 2.4 and 4.3 GPa. 223 A number of theoretical [223][224][225][226] and experimental [226][227][228][229][230][231] studies have focused on the structural transitions and properties of AlH 3 under pressure. At 1 atm AlH 3 has a large band gap, like other ionic solids.…”

The computational and experimental exploration of the phase diagrams of binary hydrides under high pressure has uncovered phases with novel stoichiometries and structures, some which are superconducting at quite high temperatures. Herein we review the plethora of studies that have been undertaken in the last decade on the main group and transition metal hydrides, as well as a few of the rare earth hydrides at pressures attainable in diamond anvil cells. The aggregate of data shows that the propensity for superconductivity is dependent upon the species used to "dope" hydrogen, with some of the highest values obtained for elements that belong to the alkaline and rare earth, or the pnictogen and chalcogen families.

“…Prior to the shock-wave pressure treatment, the samples were compacted to ∼2500 kg/m 3 to reduce sample porosity. The experiments on the shock-wave pressure treatment of MgB 2 samples were performed in the flat-type shock-wave pressure setup, made of X18H10T stainless steel [6][7][8]. Figure 1 shows the layout of the shock-wave pressure setup.…”

“…This impact generates a series of consecutive in-time planar shock pressure (up to 65 GPa) waves propagating in the sample within a few microseconds. For the current experiment, the estimated maximum temperature of the sample during the shock pressure impact is less than 1300 K [7,8]. After the shock-wave pressure treatment, the samples were extracted from the conservation cell by means of the cell boring work, for further investigation.…”

The influence of shock-wave pressure treatment up to 65 GPa on the crystal structure and the superconducting transition temperature of a polycrystalline MgB 2 sample has been investigated. X-ray diffraction measurements have revealed that the shock-wave pressure does not result in any irreversible structural phase transitions in the MgB 2 , except for microdistortions formed in the crystal structure of the shockwave pressure-treated MgB 2 sample. This conclusion is in agreement with the results of superconducting transition temperature measurements of a MgB 2 sample performed before and after its shock-wave pressure treatment.

“…In the search for effective fuel supplements in non-ideal explosives, metal hydrides have also received significant attention [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. They are promising additives to energetic materials, because of their chemical activity, high heat of combustion, and generation of low molecular weight decomposition/combustion products.…”

“…They are promising additives to energetic materials, because of their chemical activity, high heat of combustion, and generation of low molecular weight decomposition/combustion products. Among all the metal hydrides, MgH 2 and AlH 3 have the highest hydrogen storage capacity (7.6 and 10.1 %, respectively), and mainly for that reason they are best suited candidates for components of rocket propellants [3][4][5][6], high explosives [7][8][9][10][11][12][13], and even pyrotechnic compositions [14].…”

Detonation heats of RDX-based non-ideal explosives containing 15, 30 and 45 % of Al, (Al/ZrH 2 ), TiH 2 and ZrH 2 were measured with a water calorimeter set. To get more information on the behaviour of the additives in the detonations performed in an argon atmosphere, the solid post-detonation products extracted from the calorimetric bomb were analysed to determine their elemental and phase compositions. The calorimetric heats were compared with the detonation energies obtained from thermochemical calculations. All the tested explosives produce more en-ergy during detonation in the bomb than RDX itself, but only aluminium positively influences the total energy release. The results of thermal and XRD analyses indicate that post-detonation products contain mainly carbonaceous materials, metal oxides, unreacted hydrides and/or the metals. Unexpectedly TiH 2 is the least reactive additive. At TiH 2 content of 45 %, the heat effect is close to that of calculated with an assumption of complete inertness of the additive. Moreover TiH 2 and metallic titanium are present in the bomb residues in a significant amount.
