Silicon Pellets

Silicon Pellets are a form of silicon offered by Goodfellow as part of their range of pellet products. Silicon has a diamond cubic crystal structure and is an intrinsic semiconductor with good thermal conductivity and high resistivity. Silicon pellets can be used in semiconductor device fabrication where a source of high purity silicon is required. They are also used as an alloying agent with other metals like aluminum and copper to improve hardness and wear resistance. With their range of pellets, Goodfellow provides the convenience of purchasing small amounts of materials in pellet form for research and development applications.
