High purity metallic silicon

Compared with general metal silicon, the content of high-purity metal silicon is higher, usually above 99.9, up to 99.99. The surface of high-purity metal silicon is obviously different from metal silicon, brighter and smoother than general metal silicon. Specifications and particle size: natural block, 10-100mm, powder or customized according to customer requirements. Packaging: one metric ton in a large bag, or according to customer requirements

PRODUCT DETAILS

Product Details

Metallic silicon, also known as industrial silicon and crystalline silicon, is obtained by reducing silicon dioxide with a carbon reducing agent in a mineral furnace. It is an important raw material for the production of organic silicon, polysilicon and aluminum alloys. Metallic silicon is produced by continuous electrothermal chemical reaction in a mineral furnace using silicon dioxide, a carbonaceous reducing agent and a loosening agent as raw materials. During the smelting production process, the materials required for production are first sent to the silo of the ore furnace workshop by the raw material handling system, and then transported to the top silo of the ore furnace workshop or the storage silo of the operating platform by the conveying equipment according to the specific gravity of the materials. The furnace charge is added to the furnace by the furnace operator.
