High-pressure stable phases in mercury azide
WebOct 28, 2024 · The exploration of stable copper–nitrogen (Cu–N) compounds with high-energy-density has been challenging for a long time. Recently, through a combination of high temperatures and pressures, a new copper diazenide compound ( P 6 3 / mmc -CuN 2) has been synthesized (Binns et al 2024 J. Phys. Chem. Lett. 10 1109–1114). Web1.2.1 Crystal Structure of Parent and Martensite Phases. The β phase, i.e., high-temperature phase or parent phase, has a bcc structure, while the martensite phase has a hexagonal structure (α′ phase) or an orthorhombic structure (α″ phase). Fig. 1.1 shows the crystal …
