Silicon vs. Silica: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 23, 2023
Silicon is a chemical element, while silica is silicon dioxide, commonly found in nature as quartz.
Key Differences
Silicon is a chemical element with the symbol Si and atomic number 14. It is a hard, crystalline solid and is a key component in microelectronics and semiconductors. Silica, on the other hand, is a compound consisting of silicon and oxygen, represented as SiO2.
