Abstract
A tubular ceramic part is formed with a shoulder at an open end of the part, the tubular part is inserted in an opening provided in a horizontal plate which is disposed inside a sintering chamber so that the part is kept suspended in the chamber by means of the shoulder which rests against the edge of the opening, a shouldered cylindrical plug is inserted into the open end of the tubular part until the shoulder of the plug bears against the end of the tubular part, and the chamber is brought to sintering temperature. The invention is implemented to produce solid beta sodium alumina electrolyte tubes for sodium-sulphur electric cells.
