摘要
铍中碳化铍一直以来采用电导法检测。由于该方法灵敏度低、准确性较差、难于适应现代检测的需求。红外法测定碳是目前检测的趋势。通过探索和努力,我们确定了测定条件,实现了用高频红外碳硫仪测定铍中碳化铍。此法有较高的准确性、精密度。
Infraredray absorption method was applied to determination indirectly of Be2C in Beryllium. It is based on the special property of Be2C, which can react with acid and produce CH4, then CH4 is converted into CO2, that is measured by infrared detection. The accuracy and precision was improved.
