During the forming and machining of molybdenum and refractory metals in general, it is important to possess a good understanding of the special properties of this group of materials. If forming processes such as bending or folding are used, then these must be employed above the brittle-ductile transition temperature to ensure that the sheet can be safely worked without risk of fissuring.
How Semiconductors Work | HowSfWorks
While silicon crystals look metallic, they are not, in fact, metals. All of the outer electrons in a silicon crystal are involved in perfect covalent bonds, so they can''t move around. A pure silicon crystal is nearly an insulator-- very little electricity will flow through it.
