Near-Net-Shaping of Engineering Ceramics: Potentials and Prospects of Aqueous Injection Molding (AIM)
Abstract Aqueous injection molding (AIM) is a relatively new ceramic forming process which is recognized as one of the emerging ceramic technologies for the production of complex-shaped articles. In this technique a concentrated aqueous suspension is poured, cast or injected in an impermeable die where it solidifies and retains the shape of the inner part of the mold. Up to now, several physical principles and/or chemical reactions have been exploited for rigidization of the green body during AIM, such as gelling of water soluble or insoluble organic or inorganic additives, freezing, coagulation and hydrolysis. In the present paper the potentials and process limitations pertaining to various generic solidification types are listed, and the feasibility, performance and prospects for the industrialization of the most advanced AIM variants are discussed.
