A semiconductor metal in gray A semiconductor metal in gray and shiny appearance is the Silicon. It is also known as Industrial Silicon or Crystalline Silicon. Silicon is commonly used as an additive for non-ferrous alloys which are smelted from quartz and coke in an electric furnace. The metallic silicon can be classified on the basis of iron, calcium and magnesium contents.
According to the variation in the contents of these the silicon metal can be divided into different grades.
There are a variety of grades for the silicon metal. This can include 441, 411, 533, 2202, 3303 and 1101. These can be used for different purposes. Some of the important uses of silicon metals are the following;
1. Essential material in the solar and electronic industry.
2. The key metal for aluminum ingot foundry.
3. Used in the production of silicone resin, silicone rubber, silicone oil etc.
