Using a microwave for metal vapor crystal deposition?






Semiconductor fabs do it all the time, but in ultra high vacuum conditions.
 
It’s not like your home oven. Google it there are hundreds of papers but what do you want to do and what materials what do you want to achieve and after assembil8ng everything and spending 1-2 years making it work can you just buy what you want finished? Oh and likely the chemicals you need will kill you without all th support scrubbers

DC sputtering for the win. Magnetron sputtering [see Youtube for home made examples] does not use a microwave tube, it uses a special cathode with a magnet behind it to spiral the electrons causing more energetic impacts to the source target. Same spiral physics effect as in a microwave magnetron, just used differently. I guess spiral sputtering just didn't sound cool. Works gangbusters.

It's a misnomer. RF is not used.. Both Microwave driven MOCVD [What Kecked describes] and sputtering are slow and can result in a toxic mess at the hobby level.

There are people who do induction heating with susceptor materials to heat metals and ceramics for hobby processes in home microwaves. Basically RF induction heating. it's mostly a gimmick and great way to have a kitchen fire. I've tried it, a proper furnace wins every time.

Because of Amazon, high temerature furnaces and furnace materials are now cheaper then ever.

One needn't be a rocket surgeon to know you don't put metal in a kitchen microwave oven.

HMMMM, ask spyropyro about magnetrons

Who's spyropyro? People have actually put metal forks into Microwave ovens. The spacing of the tines can make for some spectacular effects...right before everything goes south.
