Quartz Glass Rod | Professional Fused Quartz Rod Manufacturer & Supplier in China
As a leading professional quartz rod manufacturer and quartz rod supplier in China, FGQuartz manufactures high precision quartz glass rod and fused quartz rod (SiO₂ ≥ 99.99%) for semiconductor, optical, laboratory and industrial applications. Our quartz glass rod products feature excellent dimensional accuracy, ultra-high purity, and superior mechanical and thermal performance, including industry-standard optical quartz rod and fully bespoke custom quartz rod solutions.

What Are Quartz Glass Rods?
Quartz glass rod products are cylindrical solid components made from high purity fused silica, also commonly known as fused quartz rod. Compared to hollow quartz tubes, solid quartz rods are commonly used in applications requiring structural support, optical transmission, and precision machining.
Due to their excellent purity, thermal stability, and machinability, quartz glass rod products are widely used in semiconductor equipment, optical systems, laboratory instruments and custom engineering components – making them the ideal material for optical quartz rod and high-precision custom quartz rod applications.
Key Advantages of Our Quartz Glass Rod & Fused Quartz Rod Products
Ultra High Purity
SiO₂ ≥ 99.99%, metal impurities < 20 ppm, ideal for contamination-sensitive semiconductor environments where our quartz glass rod products are widely used.
High Temperature Resistance
Stable up to 1100°C continuous operation, short-term up to 1300°C, a core performance advantage of our premium fused quartz rod range.
Excellent Mechanical Strength
Solid structure provides better rigidity compared to hollow quartz tubes, perfect for structural support applications.
