An electrode includes a network of compressed interconnected nanostructured carbon particles such as carbon nanotubes. Some nanostructured carbon particles of the network are in electrical contact with adjacent nanostructured carbon particles. Electrodes may be used in various devices, such as capacitors, electric arc furnaces, batteries, etc. A method of producing an electrode includes confining a mass of nanostructured carbon particles and densifying the confined mass of nanostructured carbon particles to form a cohesive body with sufficient contacts between adjacent nanostructured carbon particles to provide an electrical path between at least two remote points of the cohesive body. The electrodes may be sintered to induce covalent bonding between the nanostructured carbon particles at contact points to further enhance the mechanical and electrical properties of the electrodes.

A materials processing furnace provides for debinding and sintering objects and treating effluent generated by the sintering. A heating chamber maintains a controlled atmosphere for sintering the object. A vacuum pump evacuates an effluent from the heating chamber, and an injector adds a reagent to the evacuated effluent to form a mixed gas. A catalytic converter receives the mixed gas and catalyzes one or more hazardous or offensive compounds of the effluent, thereby converting the effluent to a safer and less offensive exhaust. As a result, the furnace is suitable for operation in an office environment.
