Abstract

L'invention porte sur un procédé de fabrication de nitrure de bore avec un rendement de traitement amélioré, une dimension de cristal contrôlée et une dureté d'agglomérat contrôlée. Pour contrôler la dureté d'agglomérat, du carbone peut être ajouté au BN brut comme dopant avant la première étape de cuisson dans une quantité se situant dans la plage de 4 à 20 % en poids. Pour une amélioration du rendement, le mélange de départ d'un composé du bore contenant de l'oxygène et d'une source contenant de l'azote peut être réduit en dimension de telle sorte qu'au moins l'un de a) une quantité d'au moins 15 % en poids des matières premières individuelles ou des matières premières mélangées est inférieure à 20 microns de diamètre et b) la dimension moyenne de particule est entre 1 et 60 microns (µm).
