Quartz Tube is a high-performance material by Jingge Semi widely used in optical and industrial applications due to its exceptional properties. Composed primarily of fused silica (SiO₂ ≥99.99%), it exhibits high thermal resistance (withstand temperatures up to 1200°C), low thermal expansion, and excellent UV transparency (transmittance ≥90% in UV range).
In optical fields, quartz tubes are integral to precision instruments such as atomic absorption spectrometers (e.g., slotted quartz tubes for atom-trapping), solar energy systems (enhancing light efficiency and uniformity in photovoltaic/thermal hybrid systems), and semiconductor manufacturing (as reactors or protective sleeves). Their chemical inertness and durability also make them ideal for harsh environments like laboratory equipment and high-temperature industrial processes.
