3303 Metal Silicon 10-60mm Industrial Silicon Particles

Metallic silicon, also known as industrial silicon, is a product refined from silica and carbonaceous reducing agents in a mineral thermal furnace. The main component of silicon is usually above 98.5% and below 99.99%, with other impurities such as iron, aluminum, and calcium. In China, silicon metal is usually classified into different grades such as 553, 441, 421, 3303, 2202, 1101 based on the content of iron, aluminum, and calcium. How much do you know about its current form? Let's take a look together: The downstream applications of metallic silicon mainly include organic silicon, polycrystalline silicon, and aluminum alloys. Organosilicon has high requirements for metallic silicon, requiring chemical grade, corresponding to model 421 #, followed by polycrystalline silicon, commonly used models 553 # and 441 #. Aluminum alloy has low requirements, but in recent years, the demand for organic silicon polycrystalline silicon has increased and its proportion has increased. The demand…
