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.

Applications of High Alumina 99 Al2O3 Alumina Ceramic Crucible for lab Corundum crucible

High alumina ceramic crucibles made from 99% Al2O3 are essential tools in demanding laboratory settings. This material is nearly pure alumina, also called corundum. It offers exceptional properties critical for scientific work. These crucibles withstand extreme heat. They handle temperatures easily exceeding 1700°C (3092°F). This makes them perfect for high-temperature applications. They are very strong mechanically. They resist physical wear and tear well. Chemical resistance is another major benefit. The 99% alumina composition is highly inert. It doesn’t react with most acids, alkalis, or molten salts. This purity prevents contamination of sensitive samples. It ensures analytical accuracy.

Scientists use these crucibles extensively for melting metals. They are ideal for melting precious metals like gold, silver, and platinum. They also work well for melting various alloys. Sample preparation is another key application. They are vital for fusing samples before analysis using XRF spectroscopy. They are also used in ash content determination. The crucibles hold samples securely during intense heating. Thermal analysis techniques rely on them too. Techniques like TGA and DTA use these crucibles to hold samples while measuring weight changes or heat flow under controlled heating. They provide a stable, non-reactive container.

These crucibles are suitable for sintering ceramic powders. They endure the high temperatures needed. They are also used in calcination processes. Calcination drives off volatile components from materials. The crucibles maintain integrity throughout. Handling requires some care. Avoid sudden temperature changes to prevent thermal shock. Use proper tongs designed for high temperatures. Clean them thoroughly between uses. Follow the lab’s specific protocols for cleaning. Proper care ensures long service life and reliable results. These crucibles are a fundamental part of advanced materials research and precise chemical analysis.

5 FAQs of High Alumina 99 Al2O3 Alumina Ceramic Crucible for lab Corundum crucible

What’s the max temperature for this crucible?
It withstands 1800°C continuously. Short bursts might reach 1850°C. Exceeding this risks cracking or melting. Always check your specific process temperature first.

Does it resist acids and bases?
Yes, it handles strong acids like hydrochloric and nitric acid well. It also resists strong alkalis like sodium hydroxide. Avoid hydrofluoric acid and hot concentrated phosphoric acid. These chemicals damage it.

Can it handle sudden temperature changes?
Yes, it has good thermal shock resistance. You can take it from a hot furnace to room temperature air safely. Avoid quenching it directly in water. This sudden extreme shift might cause cracks.

How do I clean it after use?
First, let it cool completely. Remove loose residue mechanically. Soak it in warm, dilute hydrochloric acid or nitric acid solution. Rinse it thoroughly with distilled water after. Dry it completely before reuse. Avoid abrasive scrubbing.

How long does this crucible last?
Lifespan depends heavily on use conditions. Key factors are the max temperature reached, the heating and cooling speed, the chemicals involved, and physical handling. With careful use avoiding extreme thermal stress and harsh chemicals, it lasts many cycles. Inspect it for cracks or erosion before each use.
