“…Typically, a plastic molding mass contains 30-60 vol.% of a liquid binder in addition to a ceramic-forming powder. Important issues related to rheology of disperse systems as applied to ceramic technology have been discussed by many authors [94][95][96][97][98][99][100][101][102][103]. The list of practical binders includes aqueous solutions of polymers (in particular, ionogenic cellulose derivatives, alginates, and acrylates) or diphilic molecules (e.g., polyvinyl alcohol or diethylene glycol) [104,105], highly viscous organic liquids (either polymers or monomers or their solutions in organic solvents polymer) [106,107].…”

Ceramic matrix composites reinforced with carbon nanotubes are becoming increasingly popular in industry due to their astonishing mechanical properties and taking into account the fact that advanced production technologies make carbon nanotubes increasingly affordable. In the present paper, the most convenient contemporary methods used for the compaction of molding masses composed of either technical ceramics or ceramic matrix composites reinforced with carbon nanotubes are surveyed. This stage that precedes debinding and sintering plays the key role in getting pore-free equal-density ceramics at the scale of mass production. The methods include: compaction in sealed and collector molds, cold isostatic and quasi-isostatic compaction; dynamic compaction methods, such as magnetic pulse, vibration, and ultrasonic compaction; extrusion, stamping, and injection; casting from aqueous and non-aqueous slips; tape and gel casting. Capabilities of mold-free approaches to produce precisely shaped ceramic bodies are also critically analyzed, including green ceramic machining and additive manufacturing technologies.
