Inverter microwave

be careful of the beryllium spacers, the dust from those is toxic and carcinogenic.

They use it because of it's amazing heat transfer and electrical insulating properties. It's like asbestos as far as inhalation hazard

Mark, exactly where are these spacers used?
What do they look like? (rough shape and size)
It sounds like it would be used for heat-sinks.

Thanks,

it is solid rings and a pink color. look up magnotron. dont know much about the other things

This part?
(from wikipedia!)
(and maybe others buried within)

I was getting the impression from this thread that they were ONLY used in the inverter microwaves.
I guess that is false.

this page: https://en.wikipedia.org/wiki/Cavity_magnetron#Health_hazards

says:

Some magnetrons have beryllium oxide (beryllia) ceramic insulators, which are dangerous if crushed and inhaled, or otherwise ingested. Single or chronic exposure can lead to berylliosis, an incurable lung condition. In addition, beryllia is listed as a confirmed human carcinogen by the IARC; therefore, broken ceramic insulators or magnetrons should not be directly handled.

and this page: https://en.wikipedia.org/wiki/Beryllium_oxide#Safety

says:

BeO is carcinogenic in powdered form and may cause a chronic allergic-type lung disease berylliosis. Once fired into solid form, it is safe to handle if not subjected to machining that generates dust, clean breakage releases little dust but crushing or grinding actions can pose a risk.[13] Beryllium oxide ceramic is not a hazardous waste under federal law in the USA.

I have salvaged many transformers from old units, but never bothered with the magnetron.

Yep it's the pink ring things. Do not eat LOL
There's usually a pair of them if I recall.. and they are in all types of oven.
