How long does a molybdenum crucible last and how can it be maintained?

The lifespan of a molybdenum crucible depends on various factors such as the frequency of use, the temperature and atmosphere it is exposed to, and the specific application it is being used for. In general, a molybdenum crucible can last for several months to a few years with proper use and maintenance.

To prolong the life of a molybdenum crucible, it is important to follow proper handling and maintenance guidelines. Here are some tips for maintaining a molybdenum crucible:

Avoid sudden temperature changes: Rapid temperature changes can cause thermal shock and lead to cracking or failure of the crucible. Always allow the crucible to cool down to room temperature before handling it.

Clean the crucible regularly: Regular cleaning can help to remove any contaminants or residue that may build up on the surface of the crucible. Use a soft cloth or brush to clean the crucible gently.

Handle the crucible with care: Avoid dropping or hitting the crucible, as this can lead to cracks or other damage.

Store the crucible properly: Store the crucible in a dry and clean environment to prevent corrosion or damage.

Use appropriate tools: When handling a molybdenum crucible, use appropriate tools such as tongs or gloves to avoid direct contact with the crucible.

By following these guidelines, the lifespan of a molybdenum crucible can be extended, and it can continue to be used for multiple applications before needing to be replaced.
