DESCRIPTION
Silicon Metal 441/553 is a grade of silicon metal, which is a crucial material used in a wide range of industries, including semiconductors, aluminum production, and chemical manufacturing. The number 441/553 refers to the percentage of silicon in the material, with 441 containing 99.0% pure silicon, and 553 containing 98.5% pure silicon.
The differences in the purity levels of these two grades of silicon metal can impact their properties and applications. For instance, 553 is more commonly used in the aluminum industry, while 441 is often used in the chemical industry.
Both 441 and 553 silicon metal are produced by melting high-purity silica with carbon in an electric arc furnace. The resulting material is then refined and crushed into various size fractions for commercial use.
We produce high-purity chemical and metallurgical grade silicon metal. Our main products are silicon metal lumps (97%/553/441/421/411/4105/3303/2202/1101.etc.)
