Transparent Quartz Glass Rod

Writer:World Quartz Date:

The quartz rod (fused silica rod) has the characteristics of high purity, heat resistance and low coefficient of thermal expansion. It serves as the material of the bridging rod for single-ended halogen lamps, optical fiber lighting, quartz fiber and semiconductor silicon chip processing, etc. (GE214 type)
