How to make glass conductive

At first I thought this was totally off-topic for sed. Then I realized that what you are talking about is turning an insulator into a semi-conductor.

Anyway, I don't know any permanent way to make glass conductive, but if you heat it up with a torch it will become conductive while it remains hot.

Apparently, if you get it hot enough, then put it in the microwave oven and turn it on, the glass will melt into a puddle. I've never done this, and it sounds dangerous, so I don't recommend it.

Anyway, if you do play with a torch, don't burn yourself or start any fires. Torches can be dangerous.

Asad,

It looks like you are trying to use stannous chloride to coat glass with a transparent film of tin oxide. Here's a description of the process and results:

I don't know of any way to speed this up, except to operate more units in parallel. Perhaps the folks at sci.chem might have some suggestions.

BTW, the maniac who did it also describes a homemade 50KV X-Ray machine. Here's some pictures of his results - pretty impressive! I like the cooked spider crab:

Here's the rest of the X-Ray Gallery:

We all could use something like this. Here's how to make it:

And here's his main page for other similarly insane experiments:

I've seen far worse X-Rays at well-funded hospitals!

I think that 'conductive glass' used in LCD manufacture for example normally uses tin oxide rather than chloride.

Either way, I'm sure you'll see some effect on light transmission.

In commercial jet transports, the pilot and copilot windshields are made conductive for anti-ice with a very thin film of gold evaporated onto the inside surface of the windshield.

I have absolutely no idea of the process involved in making them.

Do a search for 'vacuum coating'. It is not the glass that is made conductive, but a thin film of metal on the surface. Make the film thin enough, and it is tranparent. There are about five different processes used to deposit such coatings, and the process is widely used, to provide the 'anti reflection' coatings used on many lenses.

Lincolns used to have much the same thing, used as a defroster. A rock in the windshield got to be rather expensive.

Vacuum deposition, usually.

Usually vapor deposition of ITO, indium tin oxide.

I'm very skeptical about this diagram.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.

Google Indium Tin Oxide.

What about an exploding wire above the glass ? Kinetic energy does it

Evaporating under a vacuum is the easiest approach if u have a vacuum! First evaporate from nichrome wire which will stick proverbially and then if the conductivity must be lower evaporate some gold on top of that, use two filaments dont let the vacuum down between change over . Not my exploding wire at ambient pressure as an alternative.

Hi Dear,

I have follow your link

I am also performing the all process that is explained in this link. I do not blow the vapour through between the glass plates in my experiment. Could you please explain what is effact of blowing the vapour between the glass plates.

I am using tin chloride as I can find it easily. But tin oxide will work very batter I think. You can also guide me to make tin oxide from tin. It would be very batter if I succeed in making the tin oxide.

Thanks in advance,

Asad

A company in my city (in Australia) applies metals (gold etc) to almost anything as an "artistic" effect for jewllery or whatever. A few years back we had some first surface mirrors / beam splitters made by getting them to do a thin coating on the glass. The thickness of the coating affects the light transmission - getting a really thin coating might work for your application (what ever it is). You could try looking for some one who offers a similar service in your area. I think it might have been sputtered on under vacuum. Got any mates with an electron microsope - from memory they use a similar process for sample preparation. r.

Asad,

This is an electronics newsgroup. Your questions might be more appropriate over at sch.chem

Mike Monett

Yes. His questions don't make sense. Nobody could be that stupid and still survive.

I think it's some kind of troll. The alternate newsgroup, sci.skeptic, has nothing to do with the thread or with this newsgroup. I removed it from my replies.

Mike Monett

To give good coverage I think.

Doesn't the link suggest that the SnCl2 turns to SnO in this application ?
