silicon - David Darling

Silicon (Si) is a dark-gray, metalloid (or semimetallic) element (see Figure 1), which is the second most abundant element in Earth''s crust (25.7% by mass). It occurs naturally in various forms, including minerals composed of silies and those, such as quartz, composed of silicon dioxide.Silicon has a diamond-like crystal structure (see Figure 2), although it can also exist in an amorphous

Is Diamond a Conductor? - ThoughtCo

26.08.2018· Unique Mineral Qualities . Most diamonds are extremely efficient thermal conductors, but electrical insulators. Diamond conducts heat well as a result of the strong covalent bonds between carbon atoms in a diamond crystal. The thermal conductivity of natural diamond is around 22 W/(cm·K), which makes the diamond five times better at conducting heat than copper.
