CHEMICAL REACTION AT HIGH TEMPERATURE AND HIGH PRESSURE VI Polymorphic Transition in ZnP, at High Temperature and High Pressure

:1 new pressure-induced modification of zincdiphosphide, ZnP2, has been prepared by the di reel union o(zinc with phosphorus and also through the polymorphic transitions of both monoclinic and tetragonal ZnP2. The application of pressures above 20 kb combined with temperatures above 150'C is required for [be synthesis. The new modification of ZnP2 has a pseuda•cuhic cps[al symmetry with a latti...

Elasticity of CaSiO3 perovskite at high pressure and high temperature

Ab initio molecular dynamic (AIMD) simulations were performed to calculate the equation of state (EOS) of CaSiO3 perovskite at mantle pressure–temperature conditions. At temperatures above 2000 K, even though the hydrostatic crystal structure is metrically tetragonal in the pressure range of 13–123 GPa, the symmetry of the elastic moduli is consistent with cubic symmetry. Our results show that ...

consequence analysis of the leakage, ignition and explosion during high pressure sour gas injection process to the oil reservoir

there is no doubt that human being needs to become integrated with industry and industry needs to be progressed, daily. on the other hand, serious events in industrial units specially in oil industries has been shown that such damages and events are industry related ones. the consequence of such events and damages which resulted in chemical and poisoned explosions and loss of life and property ...

Low-temperature olivine rheology at high pressure

San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...
