Abstract

In this paper the influence of various parameters mechanochemical processing minerals (quartz-SiO2, taurit) used as components of the feedstock mix for SH-synthesis of composite systems with a high level of strength and thermal properties. It is shown that after mechanochemical processing minerals change the kinetic characteristics of the combustion process to ensure the direction of formation of the phase composition, structure and properties of SHS-composite. Preliminary IChO activates carbon which is directly involved in the combustion process, resulting in increased speed and combustion temperature. Variations IChO conditions allow you to change the kinetics of the process and provide a virtually complete implementation of the original components of the charge. The experiments established the most effective options for the batch IChO mixtures that allow purposefully adjust termokinetics characteristics of combustion and phase formation in the preparation of ceramic composites with high thermal and mechanical stability. The obtained values of thermal parameters characterize the synthesized material properties as a good thermal insulator, which provides a small heat loss from the heated surface.
