Abstract
Fine-particle tungsten carbide powders were prepared by high-temperature electrochemical synthesis, and their physicochemical properties were studied. The ceramics fabricated from these powders showed superior mechanical properties. The powders were found to exhibit high catalytic activity for hydrogen electrogeneration and electrodissolution.
