Ceramic hull subs?

I have not heard of this, but I do know that the hull of the deepest diving submarines (The Alfas and the K-278 Komsomolets (Mike)) is made out of a titanium alloy

I'll take titanium any day!

Me too

Ceramic has the unfortunate problem of being highly brittle, which is why it would perform rather poorly under stress (IE, in the bottom of the Ocean)...me thinks...

However, it is worth noting that ceramic materials is a wonderful absorbing medium against shocks.

Does anyone here know if ceramics have sound-absorbing qualities?

I don't know if it has any sound-absorbing qualities, but if it does, it could theoretically be used to coat the outer skin of a submarine in a shallow-depth infiltration mission, trading depth for stealth, right?

I would suggest if this technology is being pursued then they will have moved onto "Cermets".

Remember ceramics have been used in gas turbine engines for some years.
Ceramics can be very strong in both compresion and tension and have excellent "Creep" properties.

But this is old hat in materials technology now. One possible future is Cermets.

A composite structure composed of ceramic around a metal matrix at the molecular level.

I hate to break it to ya, but that sounds like a box of sinking rocks!

Also if I remember correctly both ceramics and cermets are used in the construction of Chobham Armor.
Developed in the UK and used on Challenger and Abrahms Main Battle Tanks. Pretty tough stuff eh?
