Abstract

This project explores the enhancement of ductility in Aluminum Oxide (Al₂O₃) ceramics through microstructural engineering. The goal is to combine the hardness and stability of Al₂O₃ with enhanced ductility for diverse industrial applications. Inspired by the naturally occurring Itacolumite rock, known for its complex microstructure, this research aims to replicate similar microstructural features in engineering ceramics. By doping Al₂O₃ with Titanium Dioxide (TiO₂), Boron Nitride (BN), and a pore former, while employing innovative sintering techniques, we hypothesize that these modifications will lead to a measurable increase in ductility. Despite early challenges in achieving homogeneity in sintering, promising results were observed with the addition of Al₂O₃ nanowires, which are expected to influence ductility through their interlocking, chainmail-like microstructure.
