Overview of Silicon Dioxide 

Silicon Dioxide (SiO₂), also known as silica, is a naturally occurring compound widely used in industrial, pharmaceutical, food, and chemical applications. It appears as a white, odorless, and tasteless powder with excellent thermal stability, chemical inertness, and high hardness.

Silicon Dioxide is essential in glass manufacturing, electronics, food additives, coatings, and catalysts. Its ability to act as a thickening agent, anti-caking agent, and reinforcing filler makes it a versatile ingredient across multiple industries.
