立方聚合氮(cg-N)的高温高压合成
Synthesis of Cubic Gauche Nitrogen(cg-N)under High Pressure and High Temperature
摘要
Abstract
Three-dimensional polymetric cubic gauche nitrogen(cg-N)combined with covalent N─N single bonds is an ideal high energy density material(HEDM).A series of solid molecular state-to-solid molecular state transitions(β-δ-ε-ζ-η)in nitrogen were observed in experiment upon pressurizing the molecular nitrogen up to 135.6GPa in ambient condition.Under 133.9GPa and at 2 000 K,the transparent cg-N was successfully synthesized using the double-side laser heating diamond-anvil cell(LHDAC)without any laser absorbing material.In addition,the pressure coefficient of the Raman A mode for cg-N is 1.56 cm-1/GPa at about 134GPa.关键词
