5 FAQs of 99% Alumina Ceramic Crucible for Refractory Industry

99% Alumina Ceramic Crucible FAQs: Refractory Industry Use

1. What’s the highest temperature this crucible handles?
This crucible handles temperatures up to 1750°C (3182°F) continuously. It’s ideal for most refractory material testing and processing. Avoid exceeding this limit. Doing so risks damaging the crucible. Crucible failure can happen suddenly.

2. How well does it resist sudden temperature changes?
These crucibles withstand thermal shock very well. This is due to the high-purity alumina material. They manage rapid heating and cooling cycles effectively. This property is crucial for many refractory applications. Processes involve quick temperature shifts.

3. How long does one crucible typically last?
Lifespan depends heavily on use conditions. Factors include maximum temperature reached, heating/cooling speed, and the materials melted. Frequent thermal cycling shortens life. Harsh chemical environments shorten life. With careful use, expect good service life. Replace it when cracks appear or material sticks badly.

4. What chemicals can damage this crucible?
Strong alkalis and hydrofluoric acid attack high-purity alumina. Avoid these substances. The crucible resists most acids and other chemicals well. Check the specific chemistry of your process. Certain molten salts or slags might cause erosion over time. Know your material’s behavior.

5. How do I maintain this crucible?
Handle it carefully to avoid chips or cracks. Avoid mechanical shock. Let it cool slowly after use whenever possible. Remove residues gently after each use. Use appropriate tools, avoid metal scrapers. Inspect it regularly for damage. Store it in a clean, dry place.
