Overview of Corundum Crucible

Corundum crucibles, made from alumina (Al₂O₃), are highly valued for their exceptional thermal resistance and chemical stability. These crucibles are ideal for high-temperature applications, such as melting and annealing processes in laboratories and industrial settings. Corundum crucibles can withstand temperatures up to 1800°C and are resistant to most chemical reagents, making them indispensable in various scientific and manufacturing operations.

Features of Corundum Crucible

High Thermal Resistance: Can withstand temperatures up to 1800°C without degrading.

Chemical Stability: Resistant to most acids and alkalis, ensuring minimal contamination during experiments or production.

Durability: Extremely durable and long-lasting, even under harsh conditions.

Non-Reactive: Does not react with the materials being processed, preserving sample purity.

Versatility: Suitable for a wide range of applications including melting metals, glass, and ceramics.

Precision Engineering: Manufactured to tight tolerances for consistent performance and reliability.

5 FAQs of 99 high temperature alumina Refractory corundum crucible

What’s the max temperature this crucible handles?
It withstands temperatures up to 1800°C (3272°F) continuously. This makes it suitable for most high-heat lab work like melting metals or sintering ceramics. Avoid exceeding this limit to prevent damage.

Can it handle sudden temperature changes?
Yes, it resists thermal shock fairly well. You can usually heat it quickly or cool it down fast. Be careful though. Extreme, repeated shocks might still cause cracks over time. Handle it carefully when hot.

What chemicals won’t damage it?
It resists strong acids and alkalis well. It’s very stable against most molten metals and salts too. Avoid hydrofluoric acid and strong phosphoric acid. These chemicals can attack the alumina material.

How long will one crucible last?
Lifespan varies a lot. It depends on the temperature, how often you use it, and what materials you put inside. Expect many uses under normal conditions. Look for cracks, thinning walls, or excessive wear. Replace it when you see these signs.

How do I clean it after use?
Let it cool completely first. Remove any loose residue gently. Use a mild acid or alkaline wash if needed, but avoid harsh chemicals. Rinse it thoroughly with clean water. Make sure it’s completely dry before heating it again. Never clean it while it’s still hot.
