The present invention relates to methods for making thread-type resistive materials capable of conducting an electrical current. A method according to the present invention comprises processing a thread of silica monofibres using a mixture comprising a carbon-containing compound at a temperature ranging from 1000 to 1100 DEG C. The thread of silicon-containing monofibres is continuously fed into the reaction zone at a constant speed varying from 2 to 10 mm/sec. A mixture comprising an inert gas or gaseous carbon oxide as well as vapour or vapours of a dioxidised hydrocarbon liquid is also supplied continuously at a flow rate ranging from 0.50 to 3 l/min. The thread is further processed with a dioxidised hydrocarbon liquid having a molecular mass of between 300 and 600 conventional units. This invention may be used in the production of electro-conductive cloth, bands, gauze, electro-conductive matrices for composite materials, heating members, etc. |
