A silicon particle is a granular material composed of several tiny silica crystal particles, usually between 2 and 10 mm in size. Ferro silicon is an alloy composed of a variety of different proportions of silicon and iron, and the content of silicon in the composition can reach 40%-90%. The two have great differences in nature, silicon particles have high temperature corrosion resistance, high strength, excellent thermal stability and chemical stability, and iron silicon has high hardness, strength, good toughness and magnetic characteristics.
Ferro silicon is widely used in iron and steel metallurgy, casting and alloy and other fields, with other alloying elements can be used to manufacture low alloy steel, medium alloy steel, stainless steel, etc., can also be used for casting cast iron and refractory materials.
Silicon particles are mainly used in metallurgy, casting and other fields, such as for the manufacture of silicon calcium wire, silicon aluminum manganese wire and silicon aluminum alloy for casting. It is also widely used in the manufacture of high-silicon ferro silicon alloys, high-purity silicon wafers, silicon plastics and other electronic materials. The higher the purity of the silicon particle, the wider its application field. For example, silicon wafers made of 99.9999% pure silicon particles can be used to make high-tech products such as semiconductor devices and solar cells.
The production of ferro silicon is the use of quartz ore, petroleum coke and lignin as raw materials, through high temperature reduction reaction prepared. The production process of both requires professional production equipment and process flow, and requires strict control of the production link to ensure the quality and stability of the product.
Silica particles are made from natural quartz ore by crushing, washing, screening and other processes. By heating the ore powder and coke in the blast furnace, the silica and coke in the ore react to produce silica and silicon, and then remove oxides and impurities through the process of suction and filtration, and finally get silicon particles.
Due to the different production processes and raw materials of the two, the price of silicon particles and ferro silicon is also different. In general, the price of silicon particles is relatively high, and the price of ferro silicon is relatively low, but with the change of market demand and the change of supply quantity, the price will also have corresponding fluctuations.
In general, although there are big differences in the use and characteristics of silicon particles and ferro silicon, they are indispensable and important raw materials in metallurgy, casting and other fields, and play an important role in the stable operation of industrial production and improving product quality.
