Comprehensive Overview of Quartz Rods for Industrial Use
Quartz rods are specialized industrial products primarily composed of silicon dioxide. These rods possess remarkable characteristics, making them suitable for a wide array of applications across various sectors. Below is an in-depth look at their properties and uses.
Properties of Quartz Rods
Optical Characteristics
- Extensive Transmission Range: Quartz rods are transparent across a broad spectrum, ranging from 120 nm to 4500 nm, without exhibiting any absorption peaks. They maintain high levels of light transmittance in both ultraviolet and infrared wavelengths, with visible light transmittance surpassing 95% and ultraviolet transmittance exceeding 90%.
- Minimal Dispersion: This material allows light of different wavelengths to travel at similar speeds, which is crucial for ensuring the accuracy and stability of optical signals.
Thermal Characteristics
- High Temperature Resistance: With a softening point near 1730°C, quartz rods can reliably operate at temperatures up to 1100°C for prolonged durations. They can also withstand short bursts of heat exceeding 1450°C without degradation.
- Thermal Stability: These rods exhibit a favorable thermal expansion coefficient, enabling them to endure rapid temperature changes without cracking. For example, a quartz rod can be heated to 1100°C and then thrust into room-temperature water without sustaining any damage.
Chemical Characteristics
- Inertness to Chemicals: Quartz rods are highly resistant to reactions with most acids, except for hydrofluoric acid. They can safely come into contact with a variety of chemical agents, showcasing significant resilience against a wide range of substances. Their stability at elevated temperatures far exceeds that of many other materials.
