- Scope
- WARNING: Personnel applying this standard should have practical experience in formal laboratory work. This section does not address all possible security issues. It is the user's responsibility to take appropriate safety and health measures and ensure compliance with the conditions stipulated in the relevant national laws and regulations. This part specifies the determination of silicon content in ferromanganese, manganese-silicon alloy, ferromanganese nitride, metallic manganese and electrolytic manganese by molybdenum blue photometric method, potassium fluorosilicate titration method and perchloric acid gravimetric method. This part is applicable to the determination of silicon content in ferromanganese, manganese-silicon alloy, ferromanganese nitride, metallic manganese and electrolytic metallic manganese. The determination range (mass fraction): 0.001% to 30.00%. Method 1: molybdenum blue photometry, suitable for the determination of silicon content in manganese metal and electrolytic metal manganese, the measurement range (mass fraction) is 0.001-0.60%; method 2: potassium fluorosilicate titration method, suitable for silicon content in manganese-silicon alloy Determination of content, measurement range (mass fraction) 12.00% ~ 30%; method three: perchloric acid gravimetric method, suitable for the determination of silicon content in ferromanganese, manganese-silicon alloy, ferromanganese nitride, metal manganese and electrolytic metal manganese , Determination range (mass fraction) 0.50% ~ 30.00%.
