Aqueous Based Freeze-Form Extrusion Fabrication of Alumina Components (Preprint)

Abstract

Fabricating ceramic materials into complex 3-D components is typically a complicated, costly, and time-consuming process that involves diamond machining to achieve its final shape. In most cases, the initial processing is powder-based, followed by densification (sintering) at elevated temperatures. Only a few circumstances, such as fuse casting and thermal spraying, can ceramics be directly fabricated into near net-shape, fully dense ceramic components. However, these techniques require an extremely high temperature to melt the ceramic.
