Silicon metal lump
Silicon metal lump, also known as industrial silicon, is a product smelted from quartz and coke in an electric furnace. The main component of silicon is about 98% (in recent years, 99.99% of Si is also contained in silicon metal), and the rest Impurities are Fe, Al, Ca and so on.
Silicon metal lump is industrial purified silicon, mainly used in the production of organic silicon, high purity semiconductor materials and the preparation of special purpose alloys. silicon metal lump is also the main raw material for producing optical fibers. Silicon is used to increase the fluidity and toughness of aluminum and its alloys, thus providing good casting and weldability. Silicon metal lump is commonly used in the electronics, metallurgical and chemical industries. It can be said that silicon metal lump has become the basic pillar industry in the information age.
The classification of silicon metal lump is usually classified according to the content of the three main impurities of Fe, Al, Ca contained in the silicon metal lump component. According to the content of Fe, Al, Ca in silicon metal lump, silicon metal lump can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.
