Abstract
In making .beta.-alumina ceramic articles by a fast firing technique in which the green shapes of compressed powder material are sintered by passing them continuously through a tubular furnace, the furnace is sloped upwardly to give convective air flow forwardly through the furnace at a speed not less than the speed of movement of the article or other means are provided for causing such an air flow or flow of other oxygen-containing gas. An induction furnace is described having a rotating tube and automatic temperature control means.
