Application Summary AI generated
GB/T 7731.9-2008 specifies two methods—bismuth iodide photometric and inductively coupled plasma atomic emission spectrometry (ICP-AES)—for determining bismuth content in ferrotungsten. It is applied in the metallurgical industry for quality control and composition analysis of ferrotungsten alloys, which are used in steelmaking and high-temperature materials. The standard ensures accurate bismuth measurement to meet product specifications and avoid contamination in downstream applications.
