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.

Specification of Customized 99.5% Al2O3 Crucible Cylindrical Alumina Corundum Ceramic Crucible

Here’s the specification content for the customized alumina crucible:

This product is a cylindrical crucible made from high-purity alumina ceramic. It uses 99.5% Al2O3 material. This purity ensures excellent performance under tough conditions. The crucible handles very high temperatures. It works well up to 1750°C continuously. It handles even higher temperatures for shorter times. The material offers great chemical resistance. It stands up to strong acids and bases. It doesn’t react with most molten metals. This makes it very versatile.

Thermal shock resistance is another key feature. The crucible doesn’t crack easily when heated fast or cooled quickly. This is important for many lab and industrial processes. Its structure is dense and hard. This minimizes contamination of your materials. The smooth surface finish helps too. It prevents sample sticking and makes cleaning simple.

We make these crucibles to your exact needs. You choose the size. Tell us the inner diameter you require. Specify the outer diameter. Give us the exact height you need. Wall thickness is also customizable. We can adjust it based on your application. We offer different grades of alumina purity. 99.5% is standard. We can discuss other options if needed. Surface finish can be tailored. Some processes need a very smooth finish. Others might need something different. We accommodate specific requirements.

Applications of Customized 99.5% Al2O3 Crucible Cylindrical Alumina Corundum Ceramic Crucible

These customized 99.5% Al2O3 crucibles are essential tools. Their very pure alumina construction makes them incredibly tough. They resist extreme heat very well. This is vital for demanding industrial processes.

Metal foundries rely on them heavily. They melt aluminum, zinc, and their alloys effectively. The crucibles withstand the molten metal’s harsh effects. They don’t contaminate the melt. This purity ensures high-quality castings. Precious metal workers also use them. They safely melt gold, silver, and platinum group metals. The crucibles handle the intense heat needed. They maintain purity in the final product.

Research labs find them indispensable. Scientists heat various materials inside them. The crucibles offer excellent chemical stability. They don’t react with most substances. This allows accurate experimental results. They are perfect for sample preparation and analysis. Semiconductor manufacturing uses them too. They process high-purity materials like silicon. The crucibles contribute to the clean environment needed. They prevent unwanted contamination.

These crucibles handle temperatures near 1800°C reliably. They resist sudden temperature changes well. This thermal shock resistance is crucial. It prevents cracking during rapid heating or cooling. Their strength is high at operating temperatures. They won’t deform or sag easily. This ensures safe handling of molten materials. They last longer than lower purity alternatives. This reduces replacement costs and downtime.

The crucibles resist attack from many molten metals. They also resist attack from fluxes and slags. This chemical inertness protects your materials. It ensures process consistency. Users get dependable performance batch after batch. Custom sizes and shapes are available. This fits specific furnace designs or process needs. They work in electric resistance furnaces and induction furnaces.

5 FAQs of Customized 99.5% Al2O3 Crucible Cylindrical Alumina Corundum Ceramic Crucible

Customers often ask about our custom 99.5% Al2O3 alumina crucibles. Here are the top five questions answered simply.

What does 99.5% Al2O3 purity mean? This means the crucible is almost entirely aluminum oxide. Only 0.5% is other materials. This high purity ensures excellent chemical resistance. It prevents contamination of your materials during high-temperature processes. The crucible stays stable and inert.

What maximum temperature can these crucibles handle? These crucibles handle extreme heat. They withstand 1750°C continuous use. Higher temperatures are possible for short periods. The exact limit depends on your specific heating and cooling cycle. Always consider your furnace atmosphere too.

Can you really customize the crucible size? Yes, we specialize in custom sizes. Tell us your exact inner diameter, outer diameter, and height requirements. We make crucibles tailored precisely to your needs. Standard sizes are also available if they fit your application.

Is the surface smooth? Our crucibles have a very fine surface finish. This smoothness minimizes sample sticking. It makes cleaning easier between uses. A smooth surface also helps the crucible last longer under tough conditions. We achieve this through careful processing.

How long does production take for custom orders? Production time varies. It depends on the complexity of your custom size and our current workload. Generally, expect 15-30 working days after order confirmation. Contact us for urgent needs. We try to find solutions.
