Publication number: 20080308970Abstract: A process for melting powders of a semiconductor material, such as silicon, to yield a high-purity solid product. The process generally entails introducing the powder into an elevated end of a tube inclined from horizontal and, while maintaining an inert atmosphere within the tube, rotating the tube so as to agitate and cause the powder therein to flow toward an oppositely-disposed lower end of the tube while heating the tube so that the powder melts as it flows toward the lower end of the tube. The molten material is then allowed to flow freely from the lower end of the tube and subsequently solidify to form a product.Type: ApplicationFiled: June 15, 2007Publication date: December 18, 2008Applicant: GENERAL ELECTRIC COMPANYInventors: Ralf Jonczyk, James Rand, Victor Lienkong Lou
