Beschreibung
Zusammenfassung:	Methods of synthesizing a diamond material, particularly nanocrystalline diamond, diamond-like carbon and bucky diamond are provided. In particular embodiments, a composition including a carbon source, such as coal, is subjected to addition of energy, such as high energy reactive milling, producing a milling product enriched in hydrogenated tetrahedral amorphous diamond-like carbon compared to the coal. A milling product is treated with heat, acid and/or base to produce nanocrystalline diamond and/or crystalline diamond-like carbon. Energy is added to produced crystalline diamond-like carbon in particular embodiments to produce bucky diamonds. L'invention concerne des procédés de synthèse d'un matériau à base de diamant, notamment un diamant nanocristallin, un carbone de type diamant et un diamant de type "bucky". Dans des modes de réalisation particuliers, une composition contenant une source de carbone, telle que du charbon, est soumise à un ajout d'énergie, tel qu'une concentration réactive d'énergie élevée, produisant un produit de concentration enrichi en carbone de type diamant amorphe tétrahédrique hydrogéné par rapport au charbon. Le produit de concentration est traité avec de la chaleur, de l'acide et/ou une base afin de produire un diamant nanocristallin et/ou un carbone de type diamant cristallin. L'énergie est ajoutée au carbone de type diamant cristallin produit dans des modes de réalisation particuliers afin d'obtenir des diamants de type "bucky".
