Why Would Computer Companies Use Silicon In Computers?

Silicon, a chemical element with symbol Si and atomic number 14, is widely used in computer technology due to its exceptional properties that make it an ideal material for electronic devices. Silicon is the second most abundant element in the Earth’s crust, making up approximately 28% of its composition. In this article, we will explore the reasons why computer companies use silicon in computers, along with five interesting facts about this essential element.

1. Semiconductor Properties: Silicon is a semiconductor, which means it can conduct electricity under certain conditions. This property allows it to be used in the creation of transistors, the building blocks of modern electronic devices. Transistors are responsible for amplifying and switching electronic signals, making them crucial components in computers. Silicon’s ability to both conduct and insulate electricity makes it an excellent choice for transistors, as it can control the flow of electric current.

2. Abundance and Cost: Silicon is the second most abundant element on Earth, after oxygen. Its widespread availability and relatively low cost make it an attractive choice for computer manufacturers. Large quantities of pure silicon can be extracted from sand, which is composed mainly of silicon dioxide. This abundance ensures a steady supply of silicon for the production of computer components, keeping costs down.

3. Thermal Stability: Silicon has excellent thermal stability, meaning it can withstand high temperatures without losing its electrical properties. This characteristic is essential for computer components that generate a significant amount of heat, such as microprocessors. By using silicon-based materials, computer companies can ensure the longevity and reliability of their products, even under heavy workloads and demanding conditions.
