Physical principles and technological aspects of the production of gradient composites based on an oxygen-free ceramics

This article examines the technological aspects of producing a new generati on of ceramic composites functionally gradient materials. It is shown how a percolation model of the electrical conductivity of resistive systems that was modified by the authors can be used to predict the electrical and mech anical properties of composites with a high degree of accuracy. Gradient co mposites in conversion systems designed to convert an electrical energy int o heat are used as an example to demonstrate the promise of the proposed me thod as a means of optimizing the processing regimes for the production of ceramic composites having the required level of electrical and mechanical p roperties.
