Abstract

Composition réticulable appropriée pour être utilisée comme agent d'infiltration ou comme liant pour des poudres céramiques, tel que le carbure de silicium et/ou le nitrure de silicium, dans une formulation destinée à être extrudée ou moulée par injection, cette composition comprenant entre 40 et 70 % en poids d'un polysilazane de faible poids moléculaire, de 15 à 35 % en poids d'un polysilazane de poids moléculaire moyen, et de 5 à 30 % en poids d'un composé d'organosilicium ou organique insaturé contenant au moins deux groupes alkyniles. Un composé insaturé préféré est le méthylvinylecyclosilazane.
