High Purity Quartz Rods Fused Silica Rods
The quartz glass rod is made of high purity silica glass, formed by thermal drawing. Dimension is in high precision, with ultra clear surface. We have many dimensions of quartz rod in stock: 2mm, 3mm, 4mm, 5mm, 6mm, 10mm, 20mm etc. This transparent quartz rod has the characteristics of high purity, strong high temperature resistance, and low thermal expansion coefficient.
Application of Quartz Glass Rods
• Pressure bridge rod for single ended halogen lamps
• Fiber optic lighting,
• Quartz fiber manufacturing,
• Semiconductor silicon wafer processing, etc.
