This is actually a pretty good warning, I had no idea those insulators were made of a toxic material and probably most people don't. I've never tried to take a magnetron apart. I've taken apart a bunch of microwave ovens to get the transformer and magnetron, but never tried to take apart a magnetron itself. It's good that you made this video to warn people.

In the U.S. they stopped using BeO on the magnetron insulators some years back. Naturally, it's older microwaves that we find them in. The U.S. was such a huge part of China's market that they stopped making the BeO insulators anyway. I have not seen one in years. I used to think the purple or pink was an indicator but then I found out Al2O3 is also made in those same colors when required.

@terrahertz52849 жыл бұрын
That's alumina not BeO. BeO became subject to extreme regulatory controls since it is so extremely carcinogenic, and is virtually never used nowadays. Where it is used, there are supposed to be warning identifier symbols. Besides, BeO was used where high heat conductivity was needed, which is not a requirement for the vacuum seals and insulating posts of a magnetron. Alumina is harmless. Though like breathing any fine hard powder, it it won't be good for the lungs. Don't grind it.
@Aussie509 жыл бұрын
TerraHertz you are absolutely right, since making this vid I have learned a lot about the ceramics used in insulating rings and thankfully BeO is almost gone (I imagine its only some of the oldest microwaves that would still have BeO in them) but like you said, grinding anything like this into dust is bad news, so I still advise people do not smash them up!.

Quote from wikipedia: 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.

Having worked with large, large magnetrons and klystrons over a period of forty five years (airborne, shipboard, and land based swept and PAR radars), one develops a very healthy respect and wariness for these emitters. Worse, far worse than the berrilium sump dust, is the constant threat of high voltage/high gauss magnetic fields. A well functioning pack mag or klystron will operate silently, rather cool, and apparently benign. I've seen ignorant ranks badly injured, and quickly, snuggling up to hot packs as though they were common coils or motors. Don't play with these wild animals unless you have your Lion Tamer's Badge.

The common white thermal paste is zinc oxide in a silicone oil - fairly harmless as far as I know. By the way - the dangerous ceramic you are talking about here is Beryllium Oxide (sometimes called Beryllia), not simply Beryllium metal. It is used because it is one of the few materials which is both thermally very conductive and electrically very insulating. I'm a bit surprised, though, if modern microwave magnetrons still use it as there are safe substitutes which are almost as good.

You'd have to have years of expousure before the beryllium dust would become a significant risk. People's whose careers are built around Beyllium have to take care, the rest of us, the risk is so close to zero as you're more likely to hurt yoursefl trying to avoid harm from beryllium than the beryllium itself. However, anyone working with anything that produces dust, from wood, to metal , to ceramics etc should make a practice of wearing a filter mask. Do that kind of work for 20-30 years and anything will build up. Even plain sand can get you if you inhale enough of it.

In the work I do-high power broadcast transmitters-the power tubes used in them have BeO ceramic tube envelopes Broadcast transmitters that used these tubes run at high DCand RF voltages. The color of the ceramic IS NOT an indicator of the material the part is made of. Some vacuum capacitors are made from BeO ceramics.The packaging for these devices has the warnings about and also on an enclosed hazard warning sheet.If in doubt-treat ANY ceramic material on tubes or vac caps as BeO. Same with the bodies of high power semiconducters.Also in new broadcast transmitters that have solid state devices to replace tubes-the semiconductors can have BeO bodies or insulators. Best to be safe than sorry! BeO poisoning is irreversible. Also if you get cut from a Broken BeO component the cut can be slow to heal and can get infected-and the Be toxins can get into your bloodstream-Handle such parts with care and wear gloves for protection.
