In situ Fabrication of Monolithic Copper Azide

AbstractFabrication and characterization of monolithic copper azide were performed. The monolithic nanoporous copper (NPC) with interconnected pores and nanoparticles was prepared by decomposition and sintering of the ultrafine copper oxalate. The preferable monolithic NPC can be obtained through decomposition and sintering at 400°C for 30 min. Then, the available monolithic NPC was in situ reacted with the gaseous HN3 for 24 h and the monolithic NPC was transformed into monolithic copper azide. Additionally, the copper particles prepared by electrodeposition were also reacted with the gaseous HN3 under uniform conditions as a comparison. The fabricated monolithic copper azide was characterized by Fourier transform infrared (FTIR), inductively coupled plasma–optical emission spectrometry (ICP-OES), and differential scanning calorimetry (DSC).Keywords: in situ fabricationmicrochargemonolithic copper azidemonolithic nanoporous copper Additional informationFundingThis project was financially supported by a foundation item from the General Armament Department of PLA (9140A0507111BQ0107), Specialized Research Fund for the Doctoral Program of Higher Education of China (20131101110009), the Project of State Key Laboratory of Explosion Science and Technology, P.
