5 FAQs of High Pure Refractory 99% Corundum Sagger Alumina Crucible Boat Al2O3 Ceramic Parts for Gold Silver Aluminum Melting

What exactly is this crucible made of?
It’s pure alumina ceramic. We use over 99% corundum. That’s Al2O3. This material is incredibly hard and resistant to heat. It handles extreme conditions well.

How hot can I safely use it?
These crucibles tolerate temperatures up to 1800°C (3272°F). That’s plenty hot for melting gold, silver, platinum, aluminum, and copper. Don’t exceed the limit. Doing so risks damage.

What metals work best with it?
It’s ideal for precious metals like gold and silver. It also works perfectly for aluminum and copper alloys. The pure alumina resists chemical reactions with these melts. It keeps your metal clean.

How long will one crucible last?
Lifespan depends heavily on your specific use. Factors include the exact metal melted, the peak temperature reached, and how carefully you handle it. Proper care extends its life significantly. Expect many uses under normal conditions.

Are there special handling rules?
Avoid sudden, extreme temperature changes. Heat it up slowly. Let it cool down slowly too. This prevents thermal shock cracks. Never expose a cold crucible directly to high heat. Always preheat it gradually. Handle it carefully to avoid chips or cracks. Check for damage before each use.
