Abstract

La présente invention concerne un matériau à base de diamant synthétique ayant au moins deux des caractéristiques suivantes : (i) une teneur en azote égale ou supérieure à 100 ppm ; (ii) un indice de morphologie cristalline (CMI) soit inférieur à quatre (4) soit supérieur à six (6) ; (iii) une distribution uniforme d'azote dans le volume majoritaire du cristal, le volume majoritaire étant égal ou supérieur à 50% du volume total du cristal ; (iv) une faible teneur en impureté de métal de transition, 'faible' représentant moins de 100 ppm en poids ; et (v) une forme cristalline exempte de facettes mineures, 'facettes mineures' signifiant toutes les facettes autres que des facettes {100} et {111}. L'invention concerne également un procédé de production de matériau à base de diamant comprenant l'étape de mise à disposition d'une masse réactionnelle comportant suffisamment d'azote pour permettre d'obtenir un matériau à base de diamant ayant une teneur en azote égale ou supérieure à 100 ppm en combinaison avec un vecteur de métal de transition et le traitement de la masse réactionnelle à une température supérieure à 1200°C et une pression supérieure à 5 GPa.
