Title: Firing of cylindrical ceramic compact
Inventor: FUNAKI KOJI
IPC: C04B35/64
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To simply control the atmosphere of volatile components in a firing case to be optimum by setting the total surface area of ceramic compact and the volume of a firing case to satisfy a specific relation. SOLUTION: The total area R (cm2) of the surface of the ceramic compact and the volume S (cm3) of a firing case are set to satisfy the relation: 1<=S/R<=15. In the case when S/R is larger than 15, the atmosphere of volatile components in the firing case becomes thin and it becomes difficult to keep the sufficient atmosphere. For example, when β-alumina is fired, alkaline atmosphere in the firing case becomes thin, and the formation rate of β"-alumina decreases, thereby β-alumina sintered body having excellent electrical properties can not be obtained. In the case when S/R is lower than 1, the alkaline atmosphere in the firing case becomes too much thick, and sodium aluminate, which is poor in Na-ion conductivity, is formed on the surface of the β-alumina sintered body, thereby the electrical properties of the sintered body are reduced.
