Near-Net Shaping and Additive Manufacturing of Ultra-High Temperature Ceramics via Colloidal Processing
Ceramic colloidal processing routes such as slip casting, gelcasting and direct ink writing provide valuable insight into the role of interaction forces between particles, solvents, and polymeric additives in the rheology, particle packing, and strength of a ceramic green body. For …

Freeze Casting of Aqueous PAA-Stabilized Carbon Nanotube-Al2O3 Suspensions
Freeze casting is a colloidal processing technique that shows great promise for development of nanostructured materials. A ceramic nanopowder is dispersed with a polymer in water, under carefully controlled pH. The suspension is cast into a suitable mold and frozen, then de-molded and exposed to a …

Investigation of electrophoretic deposition as a fabrication technique for high performance composites
Electrophoretic deposition (EPD) is a colloidal processing method for the deposition of materials from charged nanoparticles suspended in solution with the application of an external electric field. It is an increasingly popular manufacturing method for engineered materials because of its low cost, …

Understanding How Tape Casting Titanium Diboride Shifts its Processing-Microstructure-Properties Paradigm Toward New Applications
… the first detailed studies to understand how the processing-microstructure-properties relationship of TiB2 can be shifted to explore new applications. In order to do that, TiB2 has been manufactured with a processing technique never used before, with significant porosity, exploration of which has …
