Patent ID: 8728429

Claim:
A method of manufacturing electrically conductive nanodiamond material, comprising in any operative order: providing at least one type of explosive material and at least one type of carbon-containing non-explosive material; where the carbon-containing non-explosive material incorporates at least one element or species other than nitrogen, where the element or species other than nitrogen serves as a nanodiamond acceptor dopant providing electrical conductance in diamond; where the available nitrogen in the explosive material and the carbon-containing non-explosive material is limited to a level that prevents compensation of the electrical activity of the nanodiamond acceptor dopant in the conductive nanodiamond material; mixing the explosive material with the carbon-containing non-explosive material; detonating the mixture under conditions of negative oxygen balance in the presence of a cooling medium; purifying the product of detonation from incombustible impurities; and carrying out additional processing for activation or enhancement of electrical conductance.
