-EDIT_
I should have prefaced this post by saying that this applies to amorphous ceramics only. Crystalline ceramics are a different animal and have less structural disadvantages
I'm curious about this ceramic case. Anyone have any info on ceramic cased stuff or any ceramic tech? Google doesn't turn up an awful lot at least anything I'm finding helpful. Sounds interesting.
What's there to know? Assuming you've never had a materials eng class.
Ceramics can offer middling strength, high rigidity and lighter weight than metal without interfering with RF signals. They are also usually cheaper than metals like aluminum. Glass is a ceramic (and we all know how well apple has been doing with their glass bodies).
The drawbacks to ceramics are that they have zero elastic modulus. Deform them and they will crack and break (like glass, duh) instead of bending like metal, or being able to take as much punishment as plastic.
Ceramics are pretty darn good at insulating/handling heat, but their shear strength is largely nonexistent. Crack a ceramic case and it won't be long before the entire thing rips along the crack.
Would this make a good material for electronic devices? Not modern smart-phones (which are small computers). As an internal frame material it would not allow the phone to (absorb and) dissipate enough heat, and as an exterior material you'll get cracks breaks and all sorts of other issues.
I see it as a compromise between metal and plastic that does not offer enough advantages over the two other materials used in unison.
It is no mistake that 99.99% of the phones out there are made out of metal and plastic and only use glass for the screen.
Apple decided to be different and its been a rocky road for them so far. I am not saying that it can't be done.... just don't expect any huge revolutions with ceramics.
