“…Hence searching for biodegradable alternatives but still can provide low viscosity to replace traditional ceramic additives has become a focused area of research in this field. Falkowski et al 12 and Bednarek et al 13 found monosaccharides and their derivatives were a group of effectively working processing agents for alumina suspensions with a series of advantages such as nontoxic, water soluble, inexpensive, etc. Biodegradable polymers, polyaspartic acid (PASP) and polyepoxysuccinic acid (PESA), are widely used as effective scale inhibitors even under extreme condition in water treatment 14–16 .…”

Polyaspartic acid (PASP) and polyepoxysuccinic acid (PESA) were proved to be strong biodegradable candidates to replace traditional ceramic dispersant polyacrylic acid (PAA) as evidenced by rheological measurements. At low dosages (0.2 wt%), alumina suspensions with PAA were completely flocculated, while those with PESA as dispersant obtained good dispersion, and exhibited much lower viscosity than those with PASP. With further small addition of citric acid (CA), dispersion of alumina suspensions was greatly enhanced than those with single dispersant PASP or PESA. Combination of PASP/PESA-CA as ceramic dispersant is effective in dispersing aqueous alumina suspensions until high solid loading.

“…The synthesis of these compounds have been elaborated by authors and described elsewhere as well as the properties of obtained ceramic parts [15][16][17]. Saccharides have many hydroxyl groups in a molecule; thereby the cross-linked polymer network can be created by forming hydrogen bonds between polymeric chains.…”

The paper reports the decomposition of saccharides derivatives in comparison to commercial substances during the process of binder removal from ceramic samples. The saccharides derivatives are polymers synthesized from glucose and fructose with acryloyl group in the sugar molecule. The synthesized compounds played the role of binder in the shaping of ceramic powders by gelcasting method. The method belongs to colloidal processes and allows to produce ceramic elements of complicated geometry. As ceramic powder Al 2 O 3 was used. The thermal analysis have been done on apparatus coupled with mass spectrometer. MS analysis showed what types of gasses are released to the atmosphere during the thermal decomposition of polymers. The obtained results showed important differences in decomposition of polymers obtained from commercial acrylamide, 2-hydroxyethyl acrylate and N,N 0 -methylenebisacrylamide in comparison to synthesized glucose and fructose derivatives. The measurements allowed to establish the sintering program of the green ceramic samples and evaluate whether harmful NO x gases are released to the atmosphere.

“…The sintering process generates a clean burnout on using saccharide-based derivatives compared to the conventionally used organic additives. Organic synthesis allows for modification of saccharides in different functional groups thereby opening a new range of applications in ceramic technology [89].…”

Colloidal processing of ceramics has gained significant attention in recent years owing to its widespread application in biomedical and various industrial sectors. Polymer-assisted colloidal synthesis offers additional advantages and possibilities for development of advanced ceramic materials. This review enumerates the ancient techniques for ceramic production, the factors influencing the surface chemistry in colloidal processing of ceramics, together with the description of the interparticle forces, such as electrostatic and van der Waals interaction, steric and depletion, that contribute majorly to surface chemistry involved in colloidal processing of ceramics. The literature pertaining to the surface chemical interactions of various ceramic materials with polymeric additives are surveyed. Finally, the developments underlying major advancements in colloidal processing of ceramic materials are highlighted.
