GB/T 4333.2-2023 《Ferrosilicon—Determination of phosphorus content—Bismuth phosphomolybdate blue spectrophotometric method》 Related products

This standard describes in detail the method for the determination of phosphorus content in ferrosilicon using the Bismuth Phosphorus Molybdenum Blue Spectrophotometric method, spectra-trophotometry. It is suitable for the determination of phosphorus content in ferrosilicon in the range of 0.010% to 0.060% mass fraction. The standard covers the taking and preparation of samples to ensure the accuracy and Reliability of measurement results. The method is widely used and can be used in production control and mass inspection to ensure that ferrosilicon products meet relevant technical requirements.
