Questions

  1. To whom it may concern, I would like to ask, in the properties of 12363-1KG product, does the ~25%S refer to the mass percentage of S in FeS or something else? I'm looking forward to your reply. Many thanks. Best regards, Huanhuan

    1 answer
    1. "~25% S" refers to the mass percentage of sulfur reported for the "Sulfur Content (S/C-Analysis)" specification for this product. The exact specification ranges between 23.00% and 27.00% sulfur, and the measured result for each batch is reported in the Certificate of Analysis.
