Tungsten Crucible Usage Precautions
Tungsten crucible is widely used in high-temperature experiments and industrial processes, but their use must follow specific precautions to ensure safety and performance. There are some usage precautions as following:
Handling Precautions
Handle with Care: Tungsten crucibles are heavy and can be physically damaged, so they should be carefully handled to avoid dropping or scratching.
Protective Gear: When handling high-temperature crucibles, always wear heat-resistant gloves, goggles, and face shields to prevent burns or splashes.
Use Proper Tools: Use appropriate tongs to handle the crucible, especially at high temperatures. Preheat the tongs if necessary to reduce thermal shock.
Temperature Control
Gradual Heating and Cooling: To avoid cracking from thermal shock, heat and cool the crucible slowly, following the manufacturer's recommended temperature limits.
Temperature Range: Ensure that the operating temperature does not exceed the maximum value specified by the manufacturer to prevent crucible failure.
Material Compatibility
Chemical Compatibility: Ensure that the material being heated is compatible with tungsten to prevent chemical reactions that could damage the crucible or contaminate the material.
Avoid Cross-Contamination: Use different crucibles for different materials. After cleaning, thoroughly inspect the crucible to prevent residual contamination.
Cleaning and Maintenance
Regular Cleaning: Clean the crucible after each use to remove any residues. Use mild cleaners to avoid scratching.
Safe Cleaning Agents: Avoid using chemicals that might react with tungsten or damage its surface.
Storage
Dry Environment: Store in a dry, clean place to prevent corrosion or damage. Avoid stacking to prevent deformation.
These precautions will ensure the safe and effective use of tungsten crucibles and extend their lifespan.
