description The claimed invention relates to a method of obtaining hard, superhard and ultrahard construction carbon materials used in aerospace and defense industries, as well as in processing hard and superhard materials. The proposed method of obtaining very hard carbon materials, comprising the exposure of a carbon-containing material to pressure and temperature, is characterized by the addition of a sulfur-containing compound, e.g. carbon disulfide, to the said carbon-containing material. The obtained high-hardness carbon material is characterized by its structure being formed by layers of fullerene molecules, 2-dimensionally polarized along the 2nd order rotation axis, said layers being bonded by covalent forces. L'invention revendiquée concerne un procédé permettant d'obtenir les matières carbonées dures, superdures et ultradures utilisées dans l'industrie aérospatiale et celle relevant du domaine de la défense, ainsi dans la transformation des matériaux durs et superdurs. Le procédé proposé qui permet d'obtenir des matières carbonées très dures comprend l'exposition d'une matière contenant du carbone à la pression et à la température, et est caractérisé par l'ajout d'un composé contenant du soufre, par ex. un disulfure de carbone, à ladite matière contenant du carbone. La matière carbonée de dureté élevée obtenue est caractérisée par sa structure formée par deux couches de molécules de fullerène, polarisées dans les 2 dimensions le long de l'axe de rotation du 2nd ordre, lesdites couches étant liées par des forces covalentes.
