NettetSilicon is the material of choice in the chip industry. Unlike the metals normally used to conduct electrical currents, silicon is a ‘semiconductor’, meaning that its conductive properties can be increased by mixing it with other materials such as phosphorus or boron. This makes it possible to turn an electrical current on or off. NettetTo make sand melt, you need to heat it to roughly 1700°C (3090°F), which is approximately the same temperature a space shuttle reaches as it re-enters earth’s atmosphere. The sand commonly used to make glass is comprised of small grains of quartz crystals, made up of molecules of silicon dioxide, which is also known as silica.
