Organic Additives in Ceramic Processing
Résumé
This article presents the basis of ceramic formulations emphasizing the specific actions of organics to adapt the raw powder properties to ceramic processing requirements. More attention is paid to the triptych dispersant, binder and plasticizer, which confers fundamental properties, i.e., stability, adapted rheology with low viscosity at high solid loadings, and green cohesion. Finally some challenges are stated for the future of ceramic formulations, which will come along the developments of new manufacturing methods, in a century where new rules will be imposed by a higher environmental awareness.
