Re: How to improve ductility of brittle materials

Be careful with the word ductility here, your ceramics under normal
conditions will almost never be ductile and melleable like a metal due
to the very nature of the covalent or ionic bonds. You can indeed
improve the toughness through microstructure control, dopants,
processing, etc... Then there are unusual cases of superplasticity,
such as that seen in fine grained zirconia materials.
