Here's something I just read about:

So I'm wondering if this microwave heating of metals can be used for
making of glassy metals. Glassy metals are based on rapid cooling of
molten metal, causing the glassy molecular structure. From what I've
read so far, this has entailed formulating metal alloys with very low
melt points. But why can't a glassy metal be made with a very high
melt-point, by microwaving an alloy formulation to be molten at very
high temp, and quickly chilling it below a melt-point that would
itself also be quite high?

This microwave heating of metals sounds like an efficient and
controllable way to get metals to very high temperatures very quickly.
It also seems like you could cut off that microwave heating very
quickly, to facilitate the quick-chilling necessary for glassy metal
formation.

Comments?

Read the material more carefully.
It is the crucible that is heated, not the metal itself.
The coatings on the crucibles are designed to absorb the microwave
radiation, the metal itself does not.
Pragmatist.
