Peculiarities of obtaining nanocomposites with organic additives and consolidated nanomaterials with given properties

Abstract

The work presents the results of the creation of consolidated nanomaterials and composite ceramics using modern methods of consolidation of ceramic materials for the synthesis of powder precursors and specified phases that self-reinforce ceramic matrices. The method of mechanosynthesis and electroconsolidation is used. The results of the use of these trends for the creation of promising composite materials are given. The use of mechanochemical synthesis of β-SiC nanoparticles in nanoreactors, involving the organic-inorganic complex (–CH3)–(SiO2)n and the modification of refractory filler powders and carbon bonds using silicon alkoxide and related gels, has been demonstrated to enable the production of composite materials. These materials are composed of SiC, WC, and ZrO2, exhibiting a minimum bending strength of 650 MPa and crack resistance ranging from 6.5–7.9 MPa m0.5. Furthermore, this method can also produce periclase-carbon materials known for their exceptional resistance to oxidation and slag.
