摘　　要：为获取X光化爆加载模拟技术研究需要的光敏炸药材料,以硝酸银溶液和乙炔气体为原料合成出酸性乙炔银,得率约为80%;利用扫描电镜、元素分析、红外、拉曼光谱、XRD等方法对产物的结构进行了表征,用佛尔哈德法对其银含量进行了滴定。结果表明,合成的样品为针状晶体,银含量约为76%,其主要成分为乙炔银-硝酸银。研究表明该制备方法可行。To obtain the light-initiated explosive for the X-rays initiation simulation technology,the silver acetylide-silver nitrate(SASN)was synthesized from nitrate-silver and acetylene with the yield of 80%.The structure of the obtained compound was identified by scanning electron microscopy,elemental analysis,XRD,IR and Raman spectrometry.The silver content of the obtained compound was determined by Volhard method.Results show that the sample forms fine needle crystals and its silver content is about 76%,which is approximately consistent with the theoretical silver content of SASN.The study shows the preparation method is feasible.
