Customized Silicon Silicon grain is a common raw material in steel smelting, for silicon grain, which contains a lot of impurities, in order to reduce the infiltration of impurities, the use of pure silicon grain in smelting, which also reduces the quality of steel due to excessive impurities. Pure silicon grain is short for ferrosilicon grain, that is, ferrosilicon inoculant, used for steelmaking, ironmaking an inoculant. In the later stage of steel smelting, a certain amount of pure silicon particleshttp://www.shenglongtrading.com/silicon/
