Silicon manganese powder is an alloy powder composed of manganese, silicon, iron, a small amount of carbon, and other elements. It is a widely used and high-yield ferroalloy. Its consumption ranks second among electric furnace ferroalloy products. Manganese and silicon in manganese silicon alloys have a strong affinity for oxygen. When manganese silicon alloys are used in steelmaking, the deoxidation products MnSiO3 and Mn2SiO4 produced have melting points of 1270 ℃ and 1327 ℃, respectively. They have the advantages of low melting point, large particles, easy floating, and good deoxidation effect. Under the same conditions, using manganese or silicon for deoxidation alone resulted in burn loss rates of 46% and 37%, respectively, while using manganese silicon alloy for deoxidation resulted in burn loss rates of 29% for both.

Silicon manganese is a chemical compound containing both silicon and manganese elements, typically present in the form of an alloy.

Basic properties: Silicon manganese is a gray black solid with high melting point, good physical properties, stability and corrosion resistance at high temperatures.
