Abstract :
Highperformanceceramics,e.g.,siliconcarbide(SiC),canwidelybeusedinthenuclearsectorbecauseoftheirexcellentthermochemicalandradiologicalproperties.However,ithasnotbeenpossibletoutilisethisgreatpotentialsincethetechnologiesforhightemperatureresistantjoiningoftheseceramicmaterialsarenotyetsatisfying.
