【 摘 要 】

Nanometallocarbosilanes and organoelementoxanes represent a new class of unequaled precursors of components of promising ceramic composites. Ceramic-forming polymers (oligomers) have been synthesized in GNIICHTEOS. They can be used to obtain components of carbide and oxide CCM: nanometallocarbosilanes-precursors of SiC ceramics, modified by mixed carbides (TaxZryCz or TaxHfyCz). Organoelementoxane oligomers represent a new class of precursors for components (binders; coatings; fibers, etc.) of corundum (α-Al2O3), aluminosilicate (xAl2O3•ySiO2), yttrium aluminum (xY2O3•yAl2O3), yttrium-Aluminosilicate (xY2O3•yAl2O3•zSiO2), magnesium aluminum (xMgO•yAl2O3). yttrium-Aluminum-magnesium (xY2O3•yAl2O3•zMgO) and high-Temperature binary ceramics based on aluminum and yttrium oxides modified by oxides of refractory metals (zirconium, hafnium or chromium) compositions for the preparing high-strength high-Temperature and oxidative-resistant ceramic composites.
