• gelcasting
• alumina
• monosaccharides
• deflocculants
• low-toxic monomers

The present work shows the selected properties of some new, effectively working compounds based on monosaccharides, which can be used as: deflocculants, organic monomers and self-cross-linking compounds in colloidal processing of high quality ceramic elements. The synthesis of the new acryloyl compounds based on glucose, fructose and galactose is presented as well as their application in gelcasting technology. The influence of spatial structure of obtained monomers on rheological properties of alumina suspensions is discussed. Selected properties like density or tensile strength of ceramic green bodies are shown. The multifunctional role of monosaccharides derivatives is pointed out, as well as advantages of using them.
