Product Description


1. Introduction
Silicon metal,also known as crystalline silicon or industrial silicon,its main use is as an iron base alloy
additives.Silicon metal is made from quartz and coke in electric heating furnace smelting products, the main ingredient of silicon content in 98% (99.99% in recent years, the Si content of also included in the silicon metal), the rest of the impurities of iron, aluminum, calcium, etc.


2. Application
1). Used in aluminum:An additive to aluminum alloys,silicon is used to increase the fluidity and tenacity of Aluminum and its alloys, which enjoy good castability and weldability accordingly. 
2). Used in organic chemicals: Silicon metal is used in manufacturing a number of sorts of silicones,resins, and lubricants. 
3). Used in electronic parts: Silicon metal is used in producing monocrystalline and polycrystalline silicon of high purity for electronic parts, such as semi conductors, etc.
