Zusammenfassung:A solid seal, in particular used in electrochemical cells, comprises a continuous and solid ceramic core (1) comprising two opposing faces on which glass or vitroceramic beads (22, 23) are deposited. This seal is heated to a physically free state in order to evaporate the binders initially present in the bead paste. This makes it possible to effectively control the shape of the bead, the quantity of glass deposited and the final thickness of same, and assists degassing. The solid seal obtained is then inserted into the assembly comprising the electrochemical cell, which can then be clamped by exerting compressive stress on said seal, which relieves the cell and prevents risks of rupture.
