Quartz rods can withstand continuous temperatures exceeding 1100°C and short-term exposure up to 1450°C without deformation or performance degradation.
Quartz offers outstanding transmission in ultraviolet, visible, and infrared wavelengths, making it ideal for optical instruments, UV sterilization systems, and scientific research equipment.
The extremely low thermal expansion coefficient reduces the risk of cracking during rapid temperature changes, providing excellent thermal shock resistance.
Quartz rods resist most acids and corrosive chemicals, ensuring long service life in aggressive industrial environments.
Quartz possesses excellent dielectric properties and is commonly used in electrical and semiconductor applications where insulation is critical.
The low impurity content minimizes contamination risks in semiconductor processing, optical manufacturing, and laboratory environments.
