Saccharides Derivatives in Shaping of Ceramic Powders – New Monomers and Dispersants

Abstract:

Article Preview

Saccharides, particularly monosaccharides, as well as their derivatives, were found to be a group of effectively working processing agents in case of alumina which has been used as a solid phase of highly loaded suspensions. The synthesis of new low-toxic monomers obtained from saccharides is reported and their application in gelcasting process is presented. The synthesized monomer named 3-O-acrylic-D-glucose is an interesting alternative for the commercially available acrylic monomers. The present paper describes the properties of ceramic slurries obtained from two alumina powders of different grain size (47nm and 0.70mm) with the use of the new monomer 3-O-acrylic-D-glucose. The rheological measurements showed that new monomer can be applied not only as monomer able to polymerize in situ but also as dispersing agent for nanoalumina powders.
