“…In addition, because of the presence of several -OH groups in the saccharide molecules, the sugar-based monomers were used in gelcasting without any external crosslinking agent, contrary to other acrylic monomers which for weak, linear polymeric networks without cross-linking agents [42,43].…”

Herein, we present manifold possibilities of using saccharides and their derivatives in colloidal processing of ceramics. Sugar-based compounds are attractive alternatives for commonly used organic additives, because they are renewable materials, are non-toxic to human skin, and have a positive influence on the rheological behavior and stability of ceramic suspensions which is reflected in the properties of green and sintered bodies. The examined substances include sugar acids (galacturonic and lactobionic acid) as highly effective deflocculants for nanopowders; acryloyl derivatives of monosaccharides and sugar alcohols as organic monomers in gelcasting; polysaccharides as binders; and l-ascorbic acid as an activator of radical polymerization in gelcasting. The multifunctionality of the selected compounds as well as their thermal decomposition during sintering of ceramics is discussed. The study also reviews the related literature focusing on sugar-based compounds in ceramic processing.

Mechanical properties of gadolinium‐doped ceria (Ce0.9Gd0.1O1.95, 10GDC) green tape prepared by aqueous‐based tape casting process were characterized by tensile test and shear punch test (SPT). SPT was found to be a useful method for characterizing mechanical properties of green tapes. Microstructures and mechanical properties such as flexural modulus, bending strength, and microhardness of tapes sintered at 1,300–1,500 °C have been evaluated. Indentation fracture toughness was also determined by the method of Palmqvist cracks at different applied loads for tapes sintered at 1,500 °C. Grain size measurements showed that excessive grain growth occurred during sintering despite using 10GDC nanopowders as the starting material. However, mechanical properties of sintered tapes improved by increasing sintering temperature and the results are comparable with those reported for 10GDC in literature.

“…Polymerization process inside ceramic suspension was first used in gelcasting [4,5]. Nowadays the use of curing and gelation processes allow to obtain both dense ceramics, from large three-dimensional samples to thin tapes [6][7][8] and porous samples [9,10]. The most popular shaping methods based on in situ polymerization are for example: gel-tape casting [11], gel-electrophoresis [12], aqueous injection moulding [13] or mechanical foaming coupled with gelcasting [14].…”
