Mechanochemical Treatment, Structural Peculiarities, Properties, and Reactivity of SHS Systems Based on Natural Materials. 4. Production of SHS Ceramics Based on Mechanoactivated Materials

  • Published:
Journal of Engineering Physics and Thermophysics Aims and scope

The present paper considers the influence of mechanochemical treatment of minerals (quartz SiO2, calcite CaCO3, and wollastonite CaSiO3) used as components of the charge mixture for SH synthesis of ceramics with a high level of strength and thermal properties. A positive effect of using various modifiers in mechanochemical treatment of minerals activating the combustion process has been established. Suitable selection of modifiers provides an increase in the strength of synthesized SHS composites due to the formation in the synthesis products of wollastonite, helenite, anorthite, and aluminum nitride, and the decrease in the heat conductivity is due to the formation of an ultraporous structure of specimens. It has been shown that by varying the composition of the charge from the used natural minerals and the conditions of their mechanochemical treatment with modifiers, as well as the sizes of the synthesized specimen in the SHS regime, an object with high strength and thermal properties can be obtained.
