What sort of applications would this be used for? I see in the article housing electronics, but isn't plastic pretty good for that? Aren't ceramics super brittle?
Ceramics enter a new era with laser-welded joints

#12With the ability to weld glass to metal and now ceramic welding, the next 50 years are going to see a manufacturing revolution.

#13One reason is for electronics in extreme environments. Glass/Ceramics are more energetically stable than metals, so can withstand much higher temperatures. Think advanced sensors inside a rocket combustion chamber... while it is on.

This seem to need very high precision and until you can hand weld it, it will have limited applications comparing to Steel
- ceramics are thermally quite stable (with respect to expansion/contraction)
- ceramics do not conduct electricity
- ceramics do not melt easily
- ceramics are hard; leading to excellent longevity
- ceramics are chemically very stable
This is a pretty major thing.

Making it possible for even smaller computers.

Steel is routinely welded robotically. There are a very large number of applications where this advance in materials science will make a very large difference, keep in mind that: - ceramics are thermally quite stable (with respect to expansion/contraction) - ceramics do not conduct electricity - ceramics do not melt easily - ceramics are hard; leading to excellent longevity - ceramics are chemically very stable This…

I'm thinking the ceramics would cancel lots of the electrical noise that electronics, and electrical components, put out. You can't have a very sensitive antenna if all the components in a receiver are spewing lots of electrical signals. Making it possible for even smaller computers.
Crush it into sand? It is one of the hardest materials, one needs a harder material to crush something. Heat/cool to have it crumble does not work well either with ceramics.
Melting it into glass or something? Might not be practical due to extremely high temps required.
Using it as "pebble" in road/bridge construction? Not sure if concrete will be able to stick to it.

#20For those wondering why this matters: One reason is for electronics in extreme environments. Glass/Ceramics are more energetically stable than metals, so can withstand much higher temperatures. Think advanced sensors inside a rocket combustion chamber... while it is on.
