Talk:Chemically strengthened glass

Need an article on Ion-X glass.

edit

I need information on Ion-X glass. Could wikipedia please supply an article, or at least a section in this article?

Source for claim on difference of strength.

edit

It says that the float process-ed glass is stronger than the ion exchange processed one, but without a source.

And it's important because it's a key aspect of the competence between two brands of strengthened glass, as seen here:

"Strengthening"

edit

It's important to note that ion transfer doesn't affect the material's strength. It just introduces a beneficial residual stress that has compression near the surface, and tension in the middle. This has the effect that it takes more bending moment to fail the glass in tension because the surfaces are in compression. The tension in the middle doesn't matter because bending doesn't add much there. And the extra compressive stress on the other side is ok, because glass can take way more stress in compression than tension.

If you were to load chemically strengthened glass in pure tension, though, it would actually take less force to fail it, since there is residual tension in the middle of the specimen, and axial load adds to this over the entire cross section.

So, saying that ion exchanged glass is "stronger" is not correct. Hermanoere (talk) 20:16, 20 March 2020 (UTC)Reply
