Prolong the service life of graphite crucible

Select high quality materials: Select high purity, high quality graphite crucible materials. High purity graphite crucible has good high temperature resistance and corrosion resistance, and can better resist high temperature and chemical corrosion.

Avoid sudden temperature changes: Try to avoid the graphite crucible to suffer sudden temperature changes during use, which may lead to thermal stress and thermal expansion, accelerating the aging and rupture of the graphite crucible.

Avoid violent physical collision: during use and storage, avoid violent collision between graphite crucible and hard objects, so as not to cause damage and cracking of the surface of the graphite crucible.

Proper cleaning and maintenance: After use, proper cleaning and maintenance should be carried out in time. You can use a soft cloth or brush to gently wipe, avoid using hard items to clean it, so as not to scratch the graphite surface.

Avoid strong acid and alkali: graphite crucible for some strong acids and alkali has a certain corrosion resistance, but should try to avoid long-term exposure to strong acid and alkali environment, so as not to damage the graphite crucible.

Correct use of mandrel or fixture: During operation, use appropriate mandrel or fixture to avoid touching the graphite crucible directly with your hand to reduce possible contamination and damage.

Correct selection of high-quality materials, avoid temperature and physical impact changes, pay attention to cleaning and maintenance and avoid strong acids and alkalis and other factors, can effectively extend the service life of graphite crucible.
