1. Polycrystalline silicon: Polycrystalline silicon is a common form of industrial silicon. It is a silicon material composed of multiple grains. Polycrystalline silicon is widely used in photovoltaic, electronic devices and semiconductor industries, and is an important raw material for manufacturing solar panels and silicon wafers.
2. Monocrystalline silicon: Monocrystalline silicon is a silicon material composed of a single grain, and its lattice structure is more complete and stable. Monocrystalline silicon has excellent electronic properties and thermal conductivity, and is often used in the manufacture of high-power semiconductor devices, integrated circuits and optical components.
3. Waste heat silicon: Waste heat silicon refers to waste silicon materials generated in the manufacturing process of silicon products. Through recycling methods, after refining, it can be used again in the production of silicon products, such as electronic components, photovoltaic materials, etc., to achieve resource recycling.
4. Silicon steel: Silicon steel is an alloy material containing silicon elements. Its main components are silicon and iron. It has excellent magnetic permeability and electrical conductivity and is often used in the manufacture of electrical equipment such as motors and transformers.
5. Ferrosilicon: Ferrosilicon is an alloy material containing silicon and iron, and its silicon content is generally between 60% and 75%. Ferrosilicon can effectively improve the hardness, toughness and magnetic permeability of iron, and is widely used in metallurgy, casting and steel industry.
6. Silicon dioxide: Silicon dioxide is an inorganic compound that is widely present in nature and is commonly found in quartz, quartz sand, glass and other materials. Silicon dioxide is widely used in industrial production and can be used to make glass, ceramics, rubber, plastic, coatings and other materials.
7. Silicone: Silicone is an organic compound containing silicon element, which has excellent high temperature resistance, corrosion resistance and electrical insulation properties, and is widely used in chemical industry, building materials, medicine, agriculture and other fields.
In general, industrial silicon can be divided into many different categories according to its form, composition and use, and has a wide range of application fields and market demand.
