FIELD: chemistry.
SUBSTANCE: claimed is method of obtaining pre-ceramic fibre-forming organo-yttrium oxane alumoxanes by interaction of polyalkoxyalumoxanes with solution of yttrium acetylacetonate {[CH3(O)CCH=C(CH3)O]3Y·2.5H2O}, concentration of which is 4.5-5.0 wt % in acetoacetic ether in medium of organic solvent (hexane, toluene, ethyl alcohol, etc.) at temperature 20-50°C. Molar ratio aluminium:yttrium (Al:Y) is lower than 200, with the following distillation of solvents first at atmospheric pressure and then at reduced pressure and temperature to 150°C.
EFFECT: method makes it possible to obtain organo-yttrium oxane alumoxanes, which are precursors of infusible oxide fibres based on aluminium oxide, modified with yttrium oxides, cable of enduring high temperatures in oxidative medium.
