I believe the only other material that contracts when heated and expands when cooled is plutonium. I have always found that strange.
The delta phase of isotope 240 is the worst, must be very careful machining a piece close to
alpha because if it heats up and contracts, density goes up, and
alpha = >1, which is....bad. Just use to work in that business and I've always thought that property being unique to Pu and H20 was weird. Pardon my off topic rant all.
