Abstract

The apparatus for manufacturing an ingot includes a rotatable housing with an inner surface defining an opening therethrough along the rotational axis of the housing. The housing is rotated about the rotational axis. The housing includes a layer of insulating material located between the inner and outer surfaces of the housing. Particulate material is deposited along the inner surface while the housing is rotating and the particulate material is heated above its melting temperature while the housing is rotating, the rotational movement holding the molten particulate material in place by centrifugal force on the inner surface for forming an ingot. The method of manufacturing an ingot includes the steps of rotating a housing having an inner surface which defines an opening therethrough, the housing containing a layer of insulating material between the housing outer surface and the inner surface, depositing particulate material across the inner surface, and heating the particulate material above its melting point, the rotational movement of the housing holding the molten particulate material by centrifugal force on the inner surface for forming an ingot.
