Abstract

La présente invention concerne un procédé pour produire une céramique précurseur, par pyrolyse de pièces moulées en polymère précurseur élémentaire organique contenant de l'oxygène, les pièces moulées en polymère précurseur présentant des fils de contact dont une extrémité dépasse librement de la pièce moulée. L'extrémité des fils de contact, qui dépasse librement de la pièce moulée, est recouverte, avant pyrolyse, d'un liquide qui contient un précurseur qui est converti en céramique au cours de la pyrolyse.
