HB 5220.10-2008 Methods for chemical analysis of superalloys. Part 10: Determination of silicon content by silicon molybdenum blue photometric method (English Version)
This part specifies the principles, reagents, instruments, sample preparation, analysis steps, calculation of analysis results, tolerances and quality control and requirements for the determination of silicon content in high-temperature alloys using silicon-molybdenum blue absorption photometry. This section applies to the determination of silicon (including acid-insoluble silicon) content in high-temperature alloys. Measuring range: 0.05% ~ 1.00%.
