বিষয়ে Silicon
Silicon is a hard, brittle crystalline solid with a blue-gray metallic luster. It is the second most abundant element in Earth's crust after oxygen. Ultra-pure silicon is essential for semiconductor devices. Silicon plays a role in biology for diatoms and some plants.
Uses & Applications
Semiconductors and computer chips, solar cells, silicone rubber and sealants, glass manufacturing, and concrete.
মজা কথা
Silicon Valley is named after this element because it is the key material in the semiconductor chips that power the tech industry.
