低温氮吸附法研究六硝基六氮杂异伍兹烷的比表面积

Study on low temperature nitrogen adsorption of hexanitrohexaazai sowurzitane specific surface area

研究了NOVAe系列全自动比表面及孔隙度分析仪低温氮吸附法测定六硝基六氮杂异伍兹烷（HNI W）的比表面积。主要研究了HNI W的质量、脱气方式和时间对其比表面积测定值的影响,确定了较佳的测量质量和脱气时间。此外还研究了不同结晶工艺条件对制得的HNI W的比表面积的影响。

The hexanitrohexaazaisowurzitane（HNIW） specific surface area has been measured by the method of low-temperature nitrogen adsorption by the NOVA e series surface area and porosity automatic analyzer.The factors affecting on the measurement,such as the quality of HNIW,the degassing manner and timing,have been studied.As a result,the better measurement quality of HNIW and the degassing time have been determined.In addition,the effects of different HNIW crystallization processing conditions on specific surface area have been discussed.
