Used extensively in the semiconductor industry for manufacturing electronic components such as transistors, diodes, and integrated circuits due to its excellent semiconducting properties. It serves as the foundational material for solar cells in photovoltaic systems, converting sunlight into electricity efficiently. Silicon is also a key component in the production of silicones—polymers used in sealants, lubricants, medical devices, and water-repellent coatings. In metallurgy, it acts as an alloying agent, particularly in aluminum casting to improve strength and casting characteristics. Additionally, silicon-based materials are employed in glass and ceramic manufacturing, where they contribute to heat resistance and structural stability.
