FIELD: chemistry.
SUBSTANCE: invention can be applied in electro-chemical and electro-physical devices. Anodic galvanostatic polarisation of titanium and zircon is performed with current density from 0.1 to 3.0 mA·cm-2 in liquor of chlorides of alkaline metals, with contain from 0.1 to 1.0 wt % of boron carbide powder at temperature 843-873 K in argon atmosphere.
EFFECT: simplification of defect-free monolayer and poly-layer films of graphene of large area with increase of monolayer graphene output.
