Abstract Thermal initiation (∼ 300°C) of a reaction between sodium azide and anhydrous metal chlorides (LaCl3, SmCl3, TiCl3, ZrCl4, HfCl4, VCl3, TaCl5, CrCl2, WCl6 and MnCl2) in sealed evacuated ampoules rapidly produces binary metal nitrides, dinitrogen and sodium chloride. The metal nitrides were purified by trituration with methanol and characterized by powder X-ray diffraction, scanning electron
摘要在密封的抽空安瓿中,叠氮化钠与无水金属氯化物(LaCl3,SmCl3,TiCl3,ZrCl4,HfCl4,VCl3,TaCl5,CrCl2,WCl6和MnCl2)之间的反应热引发(约300°C),迅速生成二元金属氮化物,氮气和氯化钠。通过用甲醇研磨纯化金属氮化物,并通过粉末X射线衍射,扫描电子显微镜,能量色散X射线分析和FT-IR进行表征。
