在拉曼散射实验中，将通过22 GPa和32 GPa（室温）之间以及25 GPa（630 ℃）之间的冲击压力转换为非晶态的石英晶体与通过从熔体淬火产生的玻璃进行比较。非晶化过程在有两个相的转变区域中进行。强调了温度在随压力的结晶状相的演变中的作用，并证明了D-1线相关环在转化过程中的重要性。
Quartz crystal converted to the amorphous state by shock pressure between 22 GPa and 32 GPa (room temperature) and 25 GPa (630 degrees C) are compared in Raman scattering experiments with glasses produced by quenching from the melt. The amorphization process is followed in the transformation regime in which there are two phases. The role of the temperature in the evolution of the crystalline-like phase with pressure is underlined, and the importance of the D-1 line associated rings in the conversion process is demonstrated.
