copper oxide rectifiers don't deteriorate and can withstand an indefinite
short circuit - but in exchange for that ruggedness they have a very high
forward voltage drop which rises as they heat up - I tried them once and
discovered that they are very much not a precision piece of equipment

There's also the mercury arc rectifier -- although that's not a solid
state device.
I've heard that copper oxide diodes were superior in that they didn't
decay with age like their selenium counterparts (as those of us
working old radio receivers know).

Metal rectifiers are still used in things like elevators and radioI believe Selenium is still used in the power industry.
