Silicon Metal is a very important industrial product can be used in steel-making, cast iron, aluminum (aviation, aircraft & automobile parts production), and silicon optoelectronic device and many other industries. It's known as the "salt" of modern industries. Metal silicon is made from quartz and coke in electric heating furnace smelting products. The main ingredient of silicon content is about 98%. The rest of impurities is iron, aluminum and calcium etc.

Silicon Metal lump was produced in electric heating furnace by quartz and coke. Quartz will be redox and became molten silicon liquid. After cooling, it will be solid as we see. The primal silicon metal lump is very large. Then it will be made into smaller lumps which we call standard size. Silicon Metal Lumps will be 10-100mm.

The main component of metallic silicon is silicon, so it has similar properties to silicon. The properties of metallic silicon are similar to those of germanium, lead, and tin, and have semiconductor properties.

The classification of metallic silicon is usually based on the content of the three main impurities of iron, aluminum, and calcium contained in the metallic silicon component. According to the content of iron, aluminum, and calcium in metallic silicon, metallic silicon can be divided into different grades such as 553, 441, 411, 421, 3303, 3305, 2202, 2502, 1501, and 1101.

 

 

Factors affecting the price of silicon metal:

The price of silicon metal is affected by many factors. The supply and demand relationship of raw materials plays a decisive role in prices. If the supply of raw materials for producing silicon metal is in short supply, prices will rise; conversely, if supply is sufficient, prices will be relatively stable. Secondly, the purity of metallic silicon products will also affect the price of metallic silicon. The higher the purity, the more precise the corresponding production process will be, and the price will also increase. Thirdly, changes in market demand will also affect prices. If demand in related industries increases, the price of silicon metal may rise; conversely, a decrease in demand may lead to a price drop. In addition, factors such as government policies, production costs and market fluctuations will also have an impact on the price of silicon metal. We understand market changes and customer needs and are dedicated to providing you with competitive prices.

 

 

Industrial metal silicon powder is often used in the metallurgical casting industry as a non-ferrous alloy additive and silicon steel alloy agent to increase the hardenability of steel. Industrial silicon metal powder can also be used as a reducing agent for certain metals, such as new ceramic alloys.

In the refractory and powder metallurgy industries, metallic silicon is often used in steelmaking furnaces, kilns and kiln furniture to improve the high temperature resistance, wear resistance and oxidation resistance of the products.

Monocrystalline silicon produced through industrial silicon purification can be used in high-tech production fields such as integrated circuits and electronic components.

High-purity metallic silicon is used in many industrial areas. It is used in the production of silicon compounds, photovoltaic solar cells and electronic semiconductor silicon wafers.

High-quality silicon metal can also be used to improve the properties of existing aluminum. These properties include castability, hardness and strength. Adding metallic silicon to aluminum alloys can make them strong and lightweight.

Silicon metal is increasingly used in the automotive industry. For example, as a replacement for heavier cast iron components to reduce body weight. Among them, automobile engine blocks, tires, and wheel hubs are common parts made of cast aluminum and silicon materials.
