Metallurgical-Grade Silicon (MGS) - WikiChip
2018年3月5日 · Metallurgical-grade silicon (MSG or MG-Si) is silicon of relatively high purity in the order of 98% or higher which is used extensively in the metallurgical industry.
Silicon - Wikipedia
The properties of silicon may be used to modify alloys with metals other than iron. "Metallurgical grade" silicon is silicon of 95–99% purity. About 55% of the world consumption of metallurgical purity silicon goes for production of aluminium-silicon alloys (silumin alloys) for aluminium part casts, mainly for use in the automotive industry.
7.10: Semiconductor Grade Silicon - Chemistry LibreTexts
Metallurgical-grade silicon (MGS) The typical source material for commercial production of elemental silicon is quartzite gravel; a relatively pure form of sand (SiO 2). The first step in the synthesis of silicon is the melting and reduction of the silica in a submerged-electrode arc furnace.
