Believe it or not, magnetrons for common microwave ovens made since about 1980 have aluminum oxide insulators rather than beryllium oxide. The old amanna radarrange ones do have heryllium oxide. Since the 1990s they use pink ruby alumina to make them easier to sort when recycled. 🤓

Those symptoms you list sound just like the symptoms of getting older.

DANGER ⚠ Before attempting to remove a magnetron , Be absolutely sure to discharge the capacitor and the magnetron itself because no matter how long the unit has been unplugged , They can hold a charge that is LETHAL , And NEVER NEVER ATTEMPT TO POWER UP A MAGNETRON WITHOUT IT BEING INSTALLED IN THE MICROWAVE , Doing so will expose you to very dangerous levels of microwave radiation , If servicing a microwave yourself , It is strongly advisable to get a microwave leak detector to make sure there is no leakage of microwave radiation , In everything you do , ALWAYS PUT SAFETY FIRST!!!!!

Yes, public spirited to warn of the possible dangers of Beryllium oxide dust and what it can inflict upon the unwary. I note others have clarified the colouration of ceramic containing b-oxide and that most now use aluminium oxide instead. However, the magnets may be fun for us eternal Peter Pans, but the ion chamber is fashioned entirely from copper, therefore does have some value to scrappers

Split hairs.

Magnetron operates on about 2000 volts DC, which is derived from one transformer winding with a simple diode and capacitor. About 6 volts from separate transformer winding are used to heat the filament. Filament is mounted in the center of a circular chamber in the metal block with a high vacuum, with several small. straight channels leading radially outward into small chambers. Electrons emitted by the filament travel into the smaller chambers, where external magnets force the electrons to spin, emitting microwaves. These microwaves exit the end of the tube and are guided to the oven.

@spikester

More like 4000V DC, the 2000V you mention is AC straight from the transformer before it gets half-wave converted to DC by the diode and doubled with the capacitor.

I pulled apart a bunch of these in my younger days and I've still still got the magnets, don't have those symptoms but since finding out about beryllium I certainly won't be doing it again!

I have heard that most of the time if the ceramic insulator is white, it is most likely beryllium oxide. However if it is a pinkish colour, then it's most likely aluminum oxide. That could be not entirely true though, still take proper precautions just in case it is beryllium oxide.

the dangerous element of beryllium is breathing the dust, (caused by breaking or agitating it) beryllium is highly compatible with oxygen meaning the molecules quickly attach, then you breath it, and it attaches to your lungs. it can kill you depending on how much you breathe. it is suggested to wrap the beryllium part shown with tape.

I do not know if the magnetron sizes are standardized, but this one looks EXACTLY (same dimensions, but the insulator tube is pink on mine, not white), like the one in the microwave oven I did disassemble. It was made (magnetron) by Panasonic, model 2M167b-M73. I do not remember the brand of the microwave oven, it wasn't Panasonic tho. Some German or Swiss low cost brand. Also I doubt it has any Beryllium Oxide in the insulator thingy. I am sure it would be marked at such. I am searching myself to figure out if mine has any Beryllium without access to XRF or MS equipment. I did find some dubious claims about color (white vs pink) being indicator of anything, but I do find it not consistent, and not anything useful. Both Beryllium Oxide and Aluminium Oxide do have additives like chromium (for various reasons), and others than might change its color. Considering beryllium oxide is simply more expensive (but indeed better in thermal properties) than aluminium oxide I doubt it used for magnetrons these days, especially ones coming from Asia. One quick check is to check the weight and volume (i.e. submerging in water) and compute density. As of the Beryllium in any form (metallic Beryllium or Beryllium Oxide), especially as a dust, the exposure is not a joke. Even single dust exposure can lead to serious health issues.

So I did break one a part a cpl months back an tried to scrap all I could out of the microwave and tore it up to get to the brass stuff around the beryllium u mentioned so I definitely was exposed to it is it a sure thing? One time exposure and u get it for sure type thing?

The aluminum vanes remove the heat, there is copper inside, and steel. All of it can be recycled, the magnets can be repurposed. The ceramic can be trashed. So don't throw it away.

White ceramic seems to be just aluminum oxide. Although I'm not sure enough to recommend anyone breaking it anyway. But if it appears pink that is most probably beryllium ceramic

I gothe magnets. How do we properly dispose the magnetron?

how long until the ceramic wears away from using the microwave naturally...?

How do I safely take it apart I'm trying to get the thorium

this is the part my scrap yard will not take?

The electrons don't bounce around they are bent at 90 degree angles and spiral around. The Magnetron Vacuum tube has copper fins inside that portrude from the chamber wall. Each time an electron passes near a copper fin it generates voltage in that region. When this happens enough an RF signal is generated and then coupled to the output on the tube via an internal antenna. That output is also the copper nipple that is cold welded to seal the vacuum tube. There is no thermal cut out on the tube. Those are mounted on the magnetron and the cooking cavity! LOL!

I'm guessing that beryllium stuff you speak of wouldn't be a good cut for the product I'm dealing on the east side.
