Аннотация: An approach has been proposed for preparing polymerizable precursors to alpha-alumina and aluminumoxynitride ceramics and using them in stereolithographic fabrication of aluminum-containingceramics. With allowance for their homogeneity (optical transmission), photopolymerizability, and weightloss during thermolysis, three precursors based on aluminum chlorides (anhydrous and hexahydrate) and abasic aluminum chloride were chosen for characterization. We analyzed the behavior of the precursors duringfiring in an ammonia atmosphere for the preparation of oxynitride ceramics and during firing in air for thepreparation of alpha-alumina ceramics from homogeneous precursors. Stereolithographic 3D printing ofalpha-alumina ceramics was tested, in particular with the use of the proposed precursors in the form of photopolymerizablebinders allowing the fraction of alumina in photosuspensions to be increased.
