Discussion Overview

The discussion revolves around the creation of conductive glass, particularly in the context of building a solar-powered 3D printer. Participants explore various methods for making conductive glass, including the use of indium-tin oxide (ITO) and other materials, while also addressing the definitions and properties of conductive glass.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses interest in making their own ITO glass for a solar-powered 3D printer, questioning the effectiveness of using stannous chloride.
  • Another participant questions the necessity of conductive glass for a 3D printer with solar cells, suggesting a need for clarity on the project’s goals.
  • A participant mentions that making conductive glass is more about the learning experience and personal project engagement.
  • Several participants clarify that ITO is a crystalline substance and not a glass itself, used for coating glass to achieve conductivity.
  • There is a discussion about the nature of conductive glass, with references to amorphous alloys as examples, and a distinction made between crystalline and amorphous materials.
  • One participant suggests that an ultrathin film of silver could be an easier method to create a conductive and transparent layer on glass.

Areas of Agreement / Disagreement

Participants generally agree on the distinction between ITO as a crystalline substance and the concept of conductive glass, but there is no consensus on the best method for creating conductive glass or the necessity of it for the intended application.

Contextual Notes

There are unresolved questions regarding the effectiveness of various materials and methods for creating conductive glass, as well as the definitions and properties of conductive versus non-conductive glass.

Hi all, I have been researching conductive glass in my quest to create a solar powered 3D printer :) :).

So, I have contacted a few manufacturers in china who sell ITO glass, but it is still a little pricey, and I was wondering what the forums thoughts are on making my own ITO glass. I have seen a few videos that suggest using stannous chloride, but I wonder how effective it would be to do it from scratch?

Any suggestions??

Why would you need conductive glass for a 3D-printer with solar cells? Do you want to print the parts of the printer, too?

but it is still a little pricey
Conductivity+transparency together are very uncommon...
 
Making my own conductive glass is more of a learning process, I think it would be a really neat project, and I have time to kill since it's summer :)
 
Hi, ITO is not a glass but a crystalline substance., just one of the many representatives of the family of transparent conductive oxides (TCO). Indeed it is used for making a glass surface conductive, as in the case of solar cells and liquid crystal displays but this is still a glass with a crystalline substance on top of it, not a conductive glass. Examples of a conductive glass can be found among amorphous alloys.

Hey Alkim, thank you for the clarification. However..i'm still confused.

So iridium tin oxide is a substance, and it can be put on top of a regular piece of glass and coat it so that it becomes conductive (is that correct??)

However...what you are saying is that actually conductive glass is made of an amorphous alloy (which it seems i will have to google for more info :)

Am I correct?
 
Hi DeeJayCruiser,

That's right, indium-tin oxide, i.e. In2O3:Sn or ITO is a crystalline substance which is transparent and conductive so that it is used to make transparent electrodes by coating normal glass. Some other transparent conductive oxides are SnO2:F (FTO), ZnO:Al (AZO) and ZnO:Ga (GZO).
Metalic glasses are a completely different thing. They are just amorphous metal alloys, which conduct electricty but they are not transparent to visible light.
I guess that what you refer to as "conductive glass" is just ITO-coated glass.
 
The easiest way to make conductive and transparent cover on the glass is to cover with ultrathin film of silver
