Cleaning your TGA alumina crucible  

  Make sure you're treating your TGA Alumina Crucible right with our detailed guide on the best way to clean it! Follow these 7 tips and maintain optimal quality.

  Cleaning your TGA alumina crucible can be a daunting task, but it's important to do an effective job and maintain optimal quality. Follow this guide to learn the best method to clean your TGA alumina crucible with specialized tools and techniques.

  1. Before you get started with specialized cleaning tools, use a mild soap and water solution to pre-treat the crucible. Use a soft brush or cloth to gently scrub away any dirt and grime that is visible on the surface of the crucible. This should loosen any particles before you start using more advanced cleaning methods.

  2. Cleaning a TGA alumina crucible may seem difficult, but it is actually quite simple. The most important point to keep in mind when cleaning this type of crucible is to be gentle, as the material is very delicate. Before you start, make sure you are wearing safety goggles and gloves, then follow these steps: Gently scrub the inside and outside of the crucible with a soft brush dipped in soap and warm water. Rinse the cruciable thoroughly with distilled water, then air dry. Once the crucible has been cleaned and dried, it should be ready for use!

  3. Using physical methods such as scrubbing with a stiff bristled brush or wiping with acetone to remove dirt and residues. If stains are too severe and cannot be removed with these methods, it is recommended to replace the crucible. Contamination from particles can affect the results of the sintering process, so maintain its cleanliness regularly. 

  4. To clean a TGA alumina crucible, first preheat it in the high-temperature furnace at 800°C for about 6 hours, and then let it cool naturally before taking it out. Be sure to slowly heat up your crucible to prevent it from bursting or shattering. Once cooled, store the crucible in a dry place until you're ready to use it next.

  5. It is best to use a weak basic material such as anhydrous Na2CO3. However, one should avoid materials like NA202, NaOH, or acid (such as K2S207) because these may damage the crucible. When finished cleaning, be sure to rinse with distilled water and dry thoroughly before use.

  6. Cleaning a TGA alumina crucible involves proper usage and care. To avoid any thermal expansion cracks, make sure the amount of material you place in it does not exceed its capacity and is not too tight. Additionally, using appropriate tools for cleaning such as a soft brush or sponge can help protect the crucible from damage.
