FIELD: chemistry.
SUBSTANCE: methane undergoes thermal decomposition on polarised silicon plates at pressure 50-100 torr and temperature 1050-1150°C. Heating is carried out by passing electric current through two parallel plates of structural graphite, flexible carbon foil or coal-graphite fabric, in the gap between which silicon plates are placed. Considerable electric potential difference is formed between the plates.
EFFECT: use of the disclosed method enables to obtain nanodiamonds with size of 4-10 nm.
