Ferrochromium

1.10.3.3.2 Silicon Content of High-Carbon Ferrochromium. The silicon content of the ferrochromium should be low as it is an undesirable element in stainless steels. Low silicon content is favored by a low operating temperature, high carbon content in the ferroalloy and a basic slag. Other impurities are not known to affect the silicon content ...Study of the parameters in microwave dissolution …The accuracy was determined using three high-carbon ferrochromium reference materials: ECRM 585-1 from the Bureau of Analysed Samples, BAM 530-1 from the Bundesanstalt für Materialprüfung and BCS 204-4 from British Chemical Standards. The results were compared with those obtained using a classical dissolution procedure.
