摘要

摘要由分散在银基体中的细粒石英组成的孔隙率为 2-3%和 13% 的样品在平面回收安瓿瓶中分别受到 28、33 和 37 GPa 的冲击压缩。在孔隙率为 2-3% 的样品中，通过粉末 X 射线衍射法检测到了一种结晶高压二氧化硅相，它不同于闪长岩，可能具有单斜晶格。

Shock-Wave Transformations of Fine-Grained Quartz Dispersed in a Silver Matrix

Abstract

Samples with porosities of 2–3 and 13% consisting of fine-grained quartz dispersed in a silver matrix were subjected to shock compression up to 28, 33, and 37 GPa in planar recovery ampoules. In samples with a porosity of 2–3%, after purification from silver, along with amorphized quartz, a crystalline high pressure silicon dioxide phase was detected by powder X-ray diffraction, which differs from stishovite and presumably has a monoclinic lattice.

期刊介绍： High Temperature is an international peer reviewed journal that publishes original papers and reviews written by theoretical and experimental researchers. The journal deals with properties and processes in low-temperature plasma; thermophysical properties of substances including pure materials, mixtures and alloys; the properties in the vicinity of the critical point, equations of state; phase equilibrium; heat and mass transfer phenomena, in particular, by forced and free convections; processes of boiling and condensation, radiation, and complex heat transfer; experimental methods and apparatuses; high-temperature facilities for power engineering applications, etc. The journal reflects the current trends in thermophysical research. It presents the results of present-day experimental and theoretical studies in the processes of complex heat transfer, thermal, gas dynamic processes, and processes of heat and mass transfer, as well as the latest advances in the theoretical description of the properties of high-temperature media.
