Ceramics cannot be strengthened the same way as metals....

Can someone please confirm, that there is no such thing as solution hardening or particulate hardening in ceramics?

I believe you cannot do the processes mentioned. I'm not entirely sure why though. I just say because the ceramic will fracture.

In general ceramics are given enhanced properties by different methods to those used for simple metals and alloys .[/PLAIN] [Broken]
