Quartz glass, or fused quartz, is crafted from pure silicon dioxide, offering outstanding clarity and thermal resilience. Produced by melting high-purity quartz sand at extreme temperatures, it undergoes meticulous shaping and polishing for a flawless appearance. This glass displays remarkable resistance to heat, corrosion, and electrical conductivity. Its versatility finds application across scientific instruments, semiconductor fabrication, and optical devices, owing to its ability to transmit ultraviolet and infrared light with minimal distortion. Notably, its low thermal expansion renders it vital for precision-demanding tasks, including optical lenses and laboratory apparatus, where reliability is paramount.
