I've got this magnetron here. Is the white ceramic part aluminum oxide or beryllium oxide?
I've tried google, but everything I find says beryllium, I have a hard time believing this though. Why would it be beryllium oxide when aluminum oxide would be cheaper?
Anyway, just looking for a second opinion.
The pink ones are beryllium. Still, if you crush, cut, or break an of these, don't breath the dust just to be safe. If you need to break it up, do so while it is wet. Like under a stream of water or even under a wet towel. This will cut down on dust. Do this outside while wearing a respirator.

Because it's much better material for that purpose. Also, the total cost of the feedthrough depends on many things, not just on raw material price.
Back when we carried Mk 28 hydrogen bombs on B52 bombers regularly, once and awhile there would be a crash with the bombs loaded onboard.
They never detonated, although some had their high explosives explode. The cores of the hydrogen bombs contained a sphere of beryllium to reflect neutrons back into the fissile material.
When the bombs would have a partial detonation of the HE, the beryllium core would shatter. Beryllium dust would be spread across a large area downwind, which would sit for years as an environmental toxin. Lots of USAF and SAC personnel, and even civilians unfortunate enough to be downwind or come close to contaminated areas, contracted Berylliosis later in life.
The ring is ceramic (ie AlO2, or something similar).
The berilium is inside. It looks like metal (it IS metal) it is neither white nor pink (but ceramic may be also pink), I have seen some at cern, used as beam pipe.
And yeah, it is fucking toxic if inhalated.
this is a troll thread. thats not magnetron, its a old 80s style hard drive
pic related, THIS IS magnetron!
