metallic silicon Product description Silicon Metal, also known as crystalline silicon or industrial silicon, is mainly used as an additive for non-ferrous alloys. It is a product made by smelting quartz and coke in an electric furnace. The main element silicon content is about 98%, and the remaining impurities are iron and aluminum, Calcium, etc.Silicon metal is a silver-gray or dark gray powder with a metallic luster, and high melting point, good heat resistance, high resistivity, and superior oxidation resistance, it's called "industrial glutamate". Function 1. Silicon metal is widely used in smelting alloy elements, as a reducing agent in many kinds of metal smelting. 2. Silicon powder is regarded as an alloy additive, improving steel hardenability in the metallurgy and foundry industry. 3. It is mainly used in the production of alloys, polycrystalline silicon, organic silicon materials, and high-grade refractory. Application 1. Used in aluminum, silicon metal is 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 semiconductors, etc. Specification 1101/2202/3303/421/521/441/553 available or can be customized.
