5 FAQs of 250250100mm 1800C High Purity Alumina Ceramic Tray Al2o3 Crucible for Melting

5 FAQs About Our 250x250x100mm 1800C High Purity Alumina Ceramic Tray (Al2O3 Crucible)

What’s the maximum temperature?
This crucible handles temperatures up to 1800°C (3272°F). That’s its absolute limit. Never exceed this temperature. Going higher risks damaging the crucible fast. It might crack or fail completely. Always stay below 1800°C for safe operation.

How pure is the Alumina (Al2O3)?
We use very high purity alumina. It’s over 99.5% pure Al2O3. This high purity matters a lot. It prevents contamination of your melts. Impurities from the crucible won’t get into your metal or material. You get clean results.

Can it handle sudden temperature changes?
Yes, it handles thermal shock fairly well. You can heat it up fast or cool it down quickly. But avoid extreme, sudden temperature jumps if possible. Gradual changes are always safer. They help the crucible last longer. This toughness comes from the high purity material.

What chemicals won’t attack it?
This Al2O3 crucible resists many chemicals. It handles most acids and alkalis well. It’s great for melting metals like gold, silver, platinum, and copper. It also works well for many glasses and oxides. Check compatibility for very specific aggressive chemicals first. It’s generally very stable.

How long will it last?
Lifespan depends heavily on how you use it. Follow the temperature limit. Avoid rough handling. Prevent sudden extreme temperature shocks. Crucibles degrade faster under harsh conditions. With careful use, expect many heating cycles. It’s tough, but it’s still a ceramic. It will wear out eventually.
