Recently colloidal processes are willingly applied in fabrication of high-quality ceramic elements of complicated shape among which we can distinguish gelcasting, a method which combines conventional moulding from slips with polymer chemistry. The research made by authors concentrate on synthesis of new low-toxic monomers, which could be applied in gelcasting instead of toxic and commonly used acrylic substances. The interesting alternative for commercially monomers can be compounds synthesized on the basis of monosaccharides. The first synthesized monomer is 3-acrylic-D-glucopyranose. The application of this monomer in gelcasting process allowed to obtain rigid green ceramic specimens without adding an external cross-linking agent to a slurry, what allowed reducing amount of gases released to the atmosphere during polymer burnout.

The work reports the research on application of new monomer in gelcasting of alumina powders of different grain size 0.21mm and 0.70mm. The rheological behaviour of ceramic slurries has been first investigated. Then the properties of received green and sintered elements have been compared with those obtained with application of commercially available monomer 2-hydroxyethyl acrylate.
