Abstract:
Apparatus for melting a fusible material comprises:a housing bounding a microwave cavity and having an exit aperture; means for supplying the fusible material to be melted to the interior of the cavity; a crucible within the cavity, at least a portion of the crucible being spaced from the housing by a layer of unmelted particulate material, the crucible bounding an opening adapted to hold molten material, the crucible being formed as a solid integral element from melted and re-solidified material; means for supplying microwave energy to the cavity of such power that fusible material in the interior of the crucible is melted to form a molten material; and means for melting material between the molten material and the exit aperture of the cavity.
