                                      Large diameter quartz tubes, fabricated from high-purity silicon dioxide (SiO\u2082), are critical components in high-temperature, chemically aggressive, and optically demanding environments. This article provides a scientific overview of their material properties, structural advantages, manufacturing considerations, and application scenarios. Emphasis is placed on thermal stability, chemical inertness, optical transmission, and scalability challenges associated with large-diameter fabrication.
