Usage Guide of Transparent Quartz Glass Solid Cylinder Rod
Handling & Storage
- Handle clear quartz rods with clean gloves to prevent surface contamination and fingerprints that may affect optical performance.
- Store in clean, dry conditions with protective packaging to prevent scratches or mechanical damage.
- Avoid sudden mechanical shocks or impacts that may cause microfractures not immediately visible but potentially compromising during high-temperature applications.
Installation & Temperature Management
- When using quartz cylinder rods in high-temperature applications, implement gradual heating and cooling rates (≤5°C/min) to minimize thermal shock.
- Ensure appropriate clearance for thermal expansion when mounting in fixtures (coefficient of expansion: 5.5×10⁻⁷/°C).
- Do not exceed maximum operating temperatures: 1100°C for continuous use, 1450°C for short-term applications.
Chemical Compatibility
- While fused quartz cylinder rods resist most acids and chemicals, avoid prolonged exposure to hydrofluoric acid (HF) and hot concentrated phosphoric acid, which can etch the surface.
- At high temperatures (>1000°C), prevent contact with alkali metals, alkaline earth oxides, and metal oxides to avoid devitrification.
- For applications involving molten metals, consider protective coatings to prevent reaction with the quartz surface.
