Quartz is a hard, crystalline mineral composed of silicon dioxide (SiOâ??). It is one of the most abundant and versatile minerals on Earth, known for its durability, clarity, and resistance to weathering. In industry, quartz is primarily used in the production of glass, ceramics, and as a raw material for silicon in electronics. Its piezoelectric properties make it essential in the manufacturing of precision instruments, such as watches and oscillators, where it is used to maintain accurate timekeeping and frequency control.
