Prospects for development of electronic technologies in the production of refractories are discussed. Principles of the electron technology of refractories are given and techniques for control of electron supply in the electrochemical, thermochemical, and electrothermochemical treatment of refractory materials are described. The potential use of electromagnetic fields to increase the slag resistance of refractory linings is considered. Electronic wear as an initial stage in the wear of refractory materials is considered. Decreasing the diffusion of electrons from metal and slag to refractory may inhibit the electronic wear of refractory lining.
