The main use of quartz in technology is its role as a key component in electronic devices, primarily in the form of quartz crystals. These crystals exhibit piezoelectric properties, meaning they can generate an electric charge when subjected to mechanical stress. This characteristic makes quartz essential for timing and frequency control in devices like watches, smartphones, and computers. Additionally, quartz is used in various other technological applications, including oscillators, filters, and sensors, due to its stability, durability, and ability to maintain consistent performance across a range of temperatures. Its versatility continues to impact various sectors, including telecommunications and computing.
