Quartz rings are high-purity components made from fused silica, featuring excellent thermal stability, high-temperature resistance up to 1100°C, and low thermal expansion. They exhibit outstanding light transmittance, strong acid and corrosion resistance, as well as superior electrical insulation. With high dimensional accuracy and good mechanical strength, they are widely used in semiconductor manufacturing, high-temperature furnaces, optical devices, laboratory equipment, and photovoltaic industries, serving as sealing rings, insulation parts, and structural components in harsh environments.
