Abstract
The present invention relates to apparatus for producing tubular ceramic articles. The apparatus is comprised of a vertically positioned electrical induction furnace; a plurality of spaced concentrically arranged tubular forms, which fit and are arranged vertically within the furnace; one or more supply hoppers for holding particulate feed materials, and; supply lines to dry cast feed materials into the spaces between and around the forms. The forms may then be removed leaving separate vertical, hollow columns of particulate feed materials concentrically arranged within the furnace. The furnace is then heated causing the particulate materials to react forming a tubular ceramic article within the furnace.
