The Periodic Table of Tech

itwbennett writes "From calcium in cameras and germanium in CPUs to selenium in solar cells. Here's a look at how every single element in the periodic table is used in common tech products. For example: Scandium is used in the bulbs in metal halide lamps, which produce a white light source with a high color rendering index that resembles natural sunlight. These lights are often appropriate for the taping of television shows. ... Yttrium helps CRT televisions produce a red color. When used in a compound, it collects energy and passes it to the phosphor. ... Niobium: Lithium niobate is used in mobile phone production, incorporated into surface acoustic wave filters that convert acoustic waves into electrical signals and make smartphone touchscreens work. SAW filters also provide cell signal enhancement, and are used to produce the Apple iPad 2."
