Here's a little information:

Note the photos near the bottom, with its comments.

It seems that if you let anything made of aluminum soak in ammonia, it
will be permanently damaged. (Not surprising - as I mentioned, even
just using the pan for the WATER is a bad idea when there's ammonia
gas in the oven!)

But it could be even more dangerous than that, though there aren't
enough details here.

Anyway, just don't use an aluminum pan.
