摘要
在对核级碳化硼试样的多种分解方法进行简要介绍和分析之后 ,提出了以碳酸钙作熔剂在高温下分解试样 ,以盐酸浸取的方法 ,此方法应用于核级碳化硼中总硼、铁、铝等的测定获得了满意的结果。
A method for the decomposition of the nuclear grade boron carbide sample is proposed in this paper. The powdered boron carbide sample is mixed thoroughly with CaCO 3 and fused at 1000°C in a muffle furnace by raising the temperature at a rate of 300°C per an hour. The sample in the molten state is kept for 5 h. under 1000°C. The fused sample is cooled and extracted with H 2O and acidified with HCl. The sample solution is diluted to 250ml in a volumetric flask and used for the determination of total boron, iron and / or aluminum.
