2020-5-22 Silicon (Si) is a light chemical element that combines with oxygen and other elements to form silicates. Silicon in the form of silicates constitutes more than 25% of the Earth's crust. Silica (SiO 2) as quartz or quartzite is used to produce silicon ferroalloys and silicon metal. Demand for silicon ferroalloys is driven principally by the ...
Silicon is not the only semiconductor out there. Carbon and germanium also have similar properties. However, carbon is too brittle to use in chips. While germanium chips were used early in the computer era and the element is still sometimes used in chips today, silicon can remain a semiconductor at much higher temperatures than germanium.
