Abstract

L'invention concerne la fabrication de matériaux de très haute dureté. Le procédé faisant l'objet de l'invention est du type consistant à faire agir sur le nitrure de bore hexagonal une pression de 40 à 90 kilobars et une température de 1200 à 2400 degrés C en présence d'un catalyseur, et est caractérisé en ce qu'on utilise comme catalyseur un composé de zinc. Ledit composé peut être un oxyde, un hydroxyde, un nitrure et/ou un amide. Le nitrure de bore obtenu peut être utilisé dans des branches variées des constructions mécaniques comme outil de coupe pour un usinage hautement efficace des aciers et alliages trempés.
