FIELD: chemistry.

SUBSTANCE: invention relates to a method of producing organomagnesium oxane yttrium oxane aluminoxanes of general formula [(R**O)MgO]_k•[Al(OR)l(OR*)_x(OH)zOy]_m•[(R**O)_sY(OH)_tO_r]_p (1), where k, p=0.1–6, m=3–12; k/m+l+x+2y+z=3; s+t+2r=3; R – C_nH_2n+1, n=2–4; R* – C(CH₃)=CHC(O)OC₂H₅; R** – C(CH₃)=CHC(O)CH₃. Method comprises reacting polyalkoxyaluminoxanes with a yttrium acetylacetonate hydrate of formula {[CH₃(O)CCH=C(CH₃)O]₃Y⋅2.5H₂O} and magnesium acetylacetonate [CH₃(O)CCH=C(CH₃)O]₂Mg, or reacting organoyttrium oxane aluminoxanes with magnesium acetylacetonate, or reacting organomagnesium oxane aluminoxanes with a yttrium acetylacetonate hydrate, or reacting organoyttrium oxane aluminoxanes with organomagnesium oxane aluminoxanes in an organic solvent at temperature of 30–70 °C, followed by distilling off the solvent first at atmospheric pressure, and then under reduced pressure and temperature of up to 150 °C. Binders and impregnating compositions are disclosed.

EFFECT: organomagnesium oxane yttrium oxane aluminoxanes can be used as precursors for the preparation of components of high-purity ceramic composites based on aluminum, yttrium and magnesium oxides.
