View Quote (0 Items)Q: What is zone-refined silicon, and how does it differ from standard silicon grades?
Zone-refined silicon results from the purification of silicon by zone refining, a process that moves a narrow molten band along a silicon rod, allowing impurities to collect at one end and be removed. Repeated passes bring the material to 99.999% (5N) purity. Standard metallurgical-grade silicon is far less pure, generally in the 98-99% range, and carries metallic impurities that make it unsuitable for electronics and other precision work. Zone-refined silicon pieces are specified when trace contamination must be controlled and standard grades fall short.
Q: What is the relevance of zone-refined silicon?
The relevance of zone-refined silicon pieces lies in their form. They arrive ready to be charged directly into crucibles or deposition sources, so the purity gained through refining carries straight into melting and thin-film processes without extra handling. This makes them a practical feedstock for applications such as sputtering target production and microelectronics, where the material must go straight from purification into processing without a purity-compromising intermediate step.
Q: What industries and applications can zone-refined silicon pieces be used for?
Zone-refined silicon pieces are used where high purity is critical. In microelectronics, they serve as epoxy fillers, and they are used as feedstock for sputtering targets in thin-film and coating work. Additional applications include ceramic components such as bearings and cutting tools, pyrotechnic mixtures, custom alloys, and general industrial and research use.
Q: Are zone-refined silicon pieces suited for alloying and custom manufacturing?
Yes. Alongside their use in electronics and microelectronics, zone-refined silicon pieces are applicable to alloying, custom manufacturing, and general industrial use.
Q: What is the melting point of zone-refined silicon pieces?
The material has a melting point of 1410°C (2570°F) and a boiling point of 2355°C (4271°F), figures relevant to any process that remelts the pieces, such as crystal growth or evaporation source preparation. These temperatures also mark the operating range for the zone refining of silicon itself, since the process depends on repeatedly melting and resolidifying a narrow section of the rod.
Q: Can you supply silicon in other forms?
Yes. Atlantic Equipment Engineers also supplies silicon as high-purity powder and as standard-grade pieces, in addition to the zone-refined piece form on this page. Contact the team to discuss the purity, mesh size, or form your process requires.
