摘要： A high-efficient one-step synthesis of cubic gauche polymeric nitrogen was developed just by thermal treatment of KN$_3$ powders. Raman and infrared spectra confirm the formation of cubic gauche polymeric nitrogen. Further thermogravimetric differential scanning calorimeter measurements show that the content of cubic gauche polymeric nitrogen is as high as 1.5 wt% with high thermal stability, which is the highest content value reported so far.
