My question is about the tv picture tube tail on the back of the screen. I know the yoke with copper windings is there,but has anyone ever busted the tail off the picture tube and got the little bit of metal out of it? I have and some of it is non-magnetic...I would like to know what type of metal this is and is it worth breaking open the glass tail to get it out, thanks...junkdude1959
I would say it's not worth busting for the metal. There is a good video on Youtube about "scrapping a TV".
yeah i watched that and theres no info as to what kind of metal it is,but thanks for the reply...keep on scrappin'''
hi, i went on google to try and find out a little about the non-magnetic parts your talking about. what i found is a good direction but no real answer to your question. the parts in the back of the tube make up whats called an inline electron gun. the gun is made of heat deflecting material but thats all they say! i went onto madehow.com and used the search terms what material is a inline electron gun made of, and searched from there. i hope this helps and please share what you find. ill look more into it my self as ive wondered what they are my self thanks for the challange questions like this need to be asked so we all can be a little better at our jobs.
The film on the inside of the CRT tube is a Phosphor coating. See here: Parts of a Cathode Ray Tube
Then look here on wiki: Phosphor and there is a sections that says what is. Not sure if you can scrap it or not (assume you can), but you would have to vacuum A LOT of tubes in order to get enough to make it worth while. It is a very very thin film!
Hope it helps!
thanks,i was just wondering about the non magnetic metal in the tail end of the tube,what type it is and if it was valuable
Im still wondering what to do with the tube when i am done.
Dluback is one place. I think you have to send in pallets and pay for shipping, but I believe they actually pay for the tubes! If you want, look for other "Glass-to-Glass Recyclers" to get of the tubes, or melt them down and separate the lead out if you can. (with proper safety precautions of course)
Nope, nevermind. Re-read their e-mail to me, and it's a processing fee, not pay for fee. Oh well. The rest still applies.Quote:

According to the EPA, if a CRT tube is left intact, it is considered a "commodity", BUT the moment it gets broke, it is then "Toxic Waste".
CRT glass is coated with lead and very few "glass companies" are even taking it now. The company mentioned above, " Dlubak" is one of a few that will process this type of glass.
They will charge you to take the tubes from you, plus you also pay for freight.
Unless you are getting into E-Waste recycling in a big way, I would back off from it, as more and more States are passing Legislation concerning E-Waste.
This is a "Good Time" to get into it, BUT, be advised that each state has different laws concerning it and it is a very specialized market, so if you are just doing a few here and there, well, there are a lot of things that you can make a LOT more money on.
Good Luck !!
i work for a e-waste company and we deal with dlubak to take the glass tubes and what i was told that not many take tubes.we ship out a full transport trailer of tubes every day or two.It is not hard to dismantle a t.v but to make money of the tubes alone it is not worth it if u r a small operation or doing it in your back yard plus the safety steps and regulations r strict
I find my TV's and CRT's in the trash, so when I'm done with teardown, they go back in the trash....just with a little less cream filling
I was reading an article in National Geographic once about pollution and they were showing people in China and Africa crushing the tubes and heating the broken glass (in the same pans they eat out of!) to recover the lead.
The article said that this is what happens to many of the CRTs that get donated to non profit thrift stores and it's a big ecological problem.
Many municipalites take TVs and monitors as part of their recycling programs. I'm not really sure what happens to them after that but I suspect they sell them to some enterprise that gets the lead out of them in a safe manner. My city will take them after I've looted the copper out of them. I have to take them to the collection station but at least I can feel like I got rid of them properly.
The metal is made of cesium alloy, the filament is made from tungsten. See http://wiki.answers.com/Q/What_metal..._gun_made_from and http://www.enotes.com/how-products-e...thode-ray-tube for related answers
Welcome to the Forum 21.
Thanks for that second link, I like that site, makes for good reading.
I feel it's all up to you . The bottom line is if you collect a bucket of non ferrous metal regardless of type, in time you will have a filled 5 gal bucket worth some good money as they will pay you for SS or AL at the very least . even if it is cesium alloy you need the yard to except it as such.My yards would look at me and say WHAT !!
So if your there already taken it apart you can put the thing in a 5 gal bucket
Throw it in the shred.Quote:

HA! I'd love to see the yard guys' faces when you pull a freakin' TV tube from your shred pile and try to dump it off...Quote:

I looked up Cesium alloy & i can't seem to find any one knocking down doors for it, I suspect it's one of those alloys that once created it's only way back is as SS or AL. Since i take TV's apart I think for fun I will start to save that little guy from now on. What ya got to loose!! Pure Cesium is a hazard and pure Cesium melts at 82 degrees or so
mmmm.... Cesium... Do a google search for cesium and water. I remember that from high school chemistry.

Lol my yard has taken a rear projection tube from me before, I had forgotten to remove it before leaving, they just picked it up and tossed it in their pile..
Also once a huge flat screen tv...
Nope TV's are a complete no-go & the longer they know you the harder they will be on you if you get caught.Quote:

Good will is one thrift store that won't take tv's or monitors working or not.
thank you for doing it right.
The steel mesh in crts is worth money if you have a shipping container of it.....
It has a very low expension rate thru a range of tempatures. They use it as the two metal leads going thru glass lightbulbs.. etc.
Also, the thin glass rods on the stainless steel raygun are used by glass blowers in their art.
Thats all thats valuable inside a crt tube.
So, unless you have a way of getting rid of tons of crt glass, its not worth it....
I used to do it when I was slow and I still do it a little sometimes when I'm slow. I smash the glass and it's easier to dispose of when I put it in buckets, also the metal in side and the bAnd around is thick. There's a screen inside also, it's about 4-12lbs depending on the tv. Also there's lost of nasty particles inside so be careful and wear a respirator and gloves
Can you dispose of them that way where you live? By me the tubes can still go the trash and I am sure they break when at the dump. Not sure I would want to smash them up for the little bit of metal. Laws are different in each state make sure you know yours...Quote:

My Suggestion:
Leave them alone
Leave them intact
Don't break them
Take the Yoke, The Degaussing Wire & the circuit board if you want, but:
Leave them alone
Leave them intact
Don't break them
