Amorphous carbon particles extracted from petroleum coke combustion ash, characterized in that the particles each have a non-circular section, exhibiting a weight reduction, measured after heating at a constant temperature of 500~C in the presence of air for 60 min, of less than 30% and have an average particle diameter of 50 to 1 µm. There is further provided a composite material characterized in that the amorphous carbon particles are mixed in a matrix of organic material or inorganic material. Thus, it becomes feasible to obtain with economic efficiency amorphous carbon particles excelling in rigidity and strength and having extremely small specific surface area and pore volume and to provide a composite material whose performance has been improved by incorporation of the amorphous carbon.

Particules de carbone amorphe extraites de la cendre de combustion du coke de pétrole, caractérisées en ce que les particules ont chacune une section non circulaire, présentant une diminution de poids, mesurée après chauffage à une température constante de 500·C en présence d'air pendant 60 min, inférieure à 30 % et ont un diamètre moyen de particule de 50 à 1 µm. Il est en plus fourni une matière composite caractérisée en ce que les particules de carbone amorphe sont mélangées dans une matrice de matière organique ou de matière inorganique. Ainsi, il devient faisable d'obtenir des particules de carbone amorphe avec un rendement économique qui sont excellentes en termes de rigidité et de solidité et ayant une surface spécifique et un volume des pores extrêmement petits et de fournir une matière composite dont les performances ont été améliorées en incorporant le carbone amorphe.
