“…However, the neurotoxicity of the monomer, such as acrylamide in gel casting, limits its application due to the environment and health concern. A lot of efforts hence have been paid to develop alternative gelling agents with low toxicity or nontoxicity [15,16]. Recently, a ring-open polymerization mechanism was brought into the gel casting process [16,17].…”

A recently developed gel casting system based on water soluble epoxy resin was successfully applied to sialon ceramics. The solids loading could reach 48.9% without any pH adjustment, and all slurries exhibited shear-thinning behaviour. Flexural strengths of sialon ceramic obtained from 44.5 vol% slurry were 295.2 MPa at room temperature and 281.4 MPa at 700 1C; the microhardness was 16.5 GPa. The net-shape manufacturing of sialon ceramics could benefit from this investigation.

“…Cai et al 39) has shown an increase in strength of both gel and green body with increasing concentration of monomer, up to 20 MPa for alumina suspensions prepared at 50 vol %. This monomer showed a microstructure almost identical to the one prepared with AM, becoming a viable alternative low toxicity gelcasting system.…”

Shaping ceramic materials is a research area which has continuing innovation and excellence. Dry processing routes gave way to colloidal techniques enabling the preparation of more complex shapes for a wide and growing field of applications. Both dense and porous ceramics with improved properties can be produced. The development of colloidal processing led to the creation of the near-net-shaping concept, performed through slip casting, gelcasting and freeze casting. Even though these concepts have been used for the last few decades, different trends and combinations of these techniques are refreshing the processing strategies in recent years. New chemistries and concepts continue to emerge. This paper creates an overview of the recent trends in near-net-shaping routes, having a deeper look into gelcasting and freeze casting, since both processes are used in the preparation of tailored and custom dense and porous ceramics.

“…[14] Since the original AM was neurotoxic, low toxicity systems were investigated by different researchers, the most commonly used being methacrylamides and acrylates. [27,28] The use of glycerol monoacrylate GMA has been recently described, which has two hydroxyl groups in a molecule so that no crosslinking agent is needed, thus simplifying the procedure. [29] Table 2 summarizes some of the most commonly used additives for gel casting systems.…”

Shaping of Dense Advanced Ceramics and Coatings by Gelation of Polysaccharides

The application of the gelling properties of some polysaccharides in the consolidation of ceramics (gel casting) allows the forming of dense complex-shape samples through colloidal routes. A description of those polysaccharides, their gelling mechanisms (chemical and thermal), and their synergistic interaction with non gelling polysaccharides is revised, as well as their application in the shaping of 3D (bulk) and 2D (substrates, coatings, and laminates) ceramics. The materials obtained by this methodology show both homogeneous microstructures and high green mechanical strengths, which make possible the machining in the green state, with the corresponding costs reduction.
