precision quartz glass balls manufacturing factory
Our quartz glass balls (also known as fused silica balls or precision glass spheres) are widely used in semiconductor manufacturing, photonics, optical systems, aerospace engineering, laboratory equipment, and high-temperature industrial applications.
What Are Quartz Glass Balls?
Quartz glass balls are spherical components made from high-purity silicon dioxide (SiO₂). They are also referred to as fused quartz balls, fused silica spheres, or precision glass balls.
Compared with ordinary glass balls such as soda lime or borosilicate glass, quartz glass balls offer superior performance in extreme environments, especially in high temperature, high corrosion, and optical-grade applications.
Material Properties of Fused Silica Quartz Balls
Quartz glass is considered one of the purest technical glass materials. It provides exceptional physical and chemical stability.
✔ High purity SiO₂ content ≥ 99.95%–99.99%
✔ Extremely low thermal expansion coefficient
✔ High temperature resistance up to 1100–1300°C
✔ Excellent thermal shock resistance
✔ Superior optical transparency (UV–IR range)
✔ Strong chemical resistance (except HF acid)
✔ High electrical insulation performance
