钢中添加微量硼就能使钢的机械和工艺性能得到显著的改善。与此相应地要求分析工作者能快速、准确地进行测定。从七十年代开始,钢中微量硼的光度分析、仪器分析法报道不断增多,新的、行之有效的分离方法不断涌现。本文拟对纲中硼的光度分析,仪器分析方法以及测定中常用的分离方法和掩蔽剂作一简介。 一、钢中硼的存在形态和样品分析法 硼在钢中以固溶硼、氮化硼、氧化硼及铁碳硼化物等多种形式存在。因为它们在酸中往往溶解不完全,因而有”酸溶硼”与“酸不溶硼”之分。实际上,这种区分是相
Addition of trace amounts of boron in the steel can significantly improve the mechanical and technological properties of the steel. Accordingly, analysts are required to make quick and accurate measurements. From the seventies onwards, the trace boron in steel photometric analysis, instrumentation analysis reported increasing, new and effective separation methods continue to emerge. This article intends to outline the boron photometric analysis, instrumental analysis methods and determination of the separation methods and masking agent for a brief introduction. First, the existence of boron in steel morphology and sample analysis of boron in the steel to solid solution of boron, boron nitride, boron oxide and iron carbide borides and other forms exist. Because they are often incompletely dissolved in acid, which has “acid soluble boron” and “acid insoluble boron” of the points. In fact, this distinction is the phase
