Abstract
Tubes of .beta. alumina ceramic are produced by forming a tube of compressed finely divided powder material, e.g. finely divided crystalline .beta. alumina or finely divided powders which together will form on heating the required ceramic. This tube is passed at a uniform rate through an electric inductive furnace of open-ended tubular form having a short zone at 1600.degree.-1900.degree.C so that the tube is rapidly raised to the sintering temperature and, after a short period in the sintering zone is rapidly cooled.
