Products Description
Metal silicon, also called silicon metal or metallurgical grade silicon, is a versatile material that finds application in various industrial and technological fields. It is a gray, lustrous, and hard substance that is composed of approximately 98% silicon and 2% impurities such as iron, aluminum, and calcium. Here are the complete specifications of metal silicon:
1. Purity: Metal silicon is available in different purities varying from 98% to 99.9%. The higher the purity, the lower the concentration of impurities and the better the quality of the material.
2. Size: Metal silicon is usually supplied in the form of small, irregularly shaped grains or lumps that range in size from a few millimeters to several centimeters. The size distribution of metal silicon determines its flow properties and ease of handling.
3. Packaging: Metal silicon is packed in different types of containers depending on the requirements of the customer and the mode of transportation. It can be packed in bags, drums, or bulk containers such as silos or tankers.
4. Chemical composition: The chemical composition of metal silicon depends on the source of the raw materials and the manufacturing process used. The main component of metal silicon is silicon, which is present in concentrations of 98% to 99.9%. The remaining 2% comprises impurities such as iron, aluminum, calcium, and carbon.
5. Physical properties: Metal silicon has a melting point of around 1414°C and a boiling point of around 3265°C. It is a hard and brittle material with a density of around 2.3 g/cm³. It is a poor conductor of electricity and heat, but its high melting point and low thermal expansion make it an ideal material for high-temperature applications.
6. Applications: Metal silicon finds application in various fields such as metallurgy, chemical industry, electronics, and solar energy. In the metallurgical industry, metal silicon is used as a deoxidizer and alloying agent in the production of steel, cast iron, and non-ferrous alloys.
In the chemical industry, it is used as a reducing agent in the production of silicones, silanes, and other silicon-based compounds. In the electronics industry, metal silicon is used as a raw material for the production of semiconductors, solar cells, and other electronic components.
7. Storage: Metal silicon should be stored in a dry and cool place away from sources of heat, moisture, and oxidizing agents. It should be handled with care to avoid damage to the packaging and the material. Metal silicon should be kept away from flammable and combustible materials.
In conclusion, metal silicon is a valuable material with diverse applications in various industrial and technological fields. It is available in different purities, sizes, and packaging options to meet the needs of different customers. Metal silicon has excellent physical and chemical properties that make it an ideal material for high-temperature applications. Therefore, it is important to handle, store, and transport metal silicon with care to ensure its quality and safety.
