Bent, flattened and drawn.
Close window when finished.The technical terms to cover these characteristics are malleable and ductile. Malleable refers to ease of reshaping (e.g. turning flat slabs into tubes without cracking or breaking) and ductile refers to the ability to be drawn out, as into wires. Granite is not very malleable or ductile. Copper is.
As you can see, the shifting of a row of metal ions makes very little difference to the over-all structure.
One of the more practical challenges to those researching superconductivity is that the materials showing the most promise as high temperature* superconductors are ceramics. How do you make wires out of materials that break every time you try to bend them?
Close window to continue.
*High temperature here is a very relative term. We are talking several degrees above absolute zero, which is still nearly minus two hundred degrees Centigrade. That’s still huge progress over the state of play 10 years ago.
