"Silico-manganese adds additional silicon which is a stronger deoxidizer and which also helps to improve some mechanical properties of steel. It is lumpy material with a silvery metallic surface. Main producers of Silico Manganese are in India and China"

FERRO SILICO MANGANESE APPLICATIONS :
"Silicon and manganese acts as deoxidisers. Deoxidation with S i M n results in cleaner steel, as the liquid manganese silicate formed coagulates and separates easier from the melt, compared to solid S i O2 formed during FeSideoxidation."
