Ceramic-forming organochromiumoxane yttriumoxane alumoxanes with various Al:Cr and Al:Y mole ratios have been synthesized by the co-condensation of chelated alkoxyalumoxanes, yttrium acetylacetonate hydrate and chromium acetylacetonate organic solvent. Pyrolysis of the synthesized organochromiumoxane yttriumoxane alumoxanes at 1500°C results in the formation of high-purity multicomponent ceramics of Al 2 O 3 −Y 2 O 3 −Cr 2 O 3 composition; said ceramics was studied in detail by X-ray analysis.
