Metal Silicon is usually classified according to the content of Si, Fe, Al, Ca. Main types of silicon metal are 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, 1101 etc.

Silicon metal 553 is a commonly used grade. In the metal silicon 553, the silicon content should be as high as 98.5%.

Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth's crust (behind only oxygen) and the eighth-most common element in the universe.

silicon metal 3303 Silicon metal is a gray and shiny semiconductor metal,also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys which smelted from quartz and coke in an electric furnace.
