Specification of Alumina Al2o3 Ceramic Crucible/boat Container Ceramic Products

Alumina ceramic crucibles and boats offer excellent performance for high temperature work. These containers are made from aluminum oxide, known as Al2O3. This material is incredibly hard and durable. It withstands severe thermal shock well. Crucibles don’t crack easily when temperatures change fast. Alumina ceramic resists chemical attack effectively. Acids and alkalis generally don’t damage it. This makes it suitable for many laboratory and industrial processes. The material maintains strength at very high temperatures. It works reliably up to about 1700°C. Long exposure to high heat doesn’t weaken it much. Alumina ceramic is also a good electrical insulator. It has low thermal conductivity too. This helps control heat in sensitive applications.

Common sizes for these crucibles range from small volumes like 5ml to larger capacities over 1000ml. Boats come in various lengths and widths to fit different furnace types. Wall thickness is designed for strength and thermal efficiency. Standard purity levels are typically 95% or 99% Al2O3. Higher purity offers better performance in extreme conditions. The surface finish is usually smooth. This helps prevent material sticking inside the container. Color is naturally white or off-white. Custom shapes and sizes are often possible. Suppliers can make crucibles or boats to specific drawings. These products are widely used in metallurgy for melting metals. They serve in chemistry labs for sample preparation. The semiconductor industry uses them for crystal growth and diffusion processes. They are essential in material science research. Handling high purity materials is another key application. Alumina ceramic crucibles provide reliable service where other materials fail. They are a fundamental tool for demanding thermal applications.

Applications of Alumina Al2o3 Ceramic Crucible/boat Container Ceramic Products

Alumina ceramic crucibles and boats are important tools. They handle very hot jobs well. Alumina is aluminum oxide. This material gives these containers special abilities. They survive extreme temperatures easily. Many furnaces get incredibly hot. Alumina crucibles work fine inside them. Heat does not damage them quickly. They last a long time under fire.

Chemical attack is another problem. Harsh acids or bases ruin many materials. Alumina ceramic resists this damage effectively. It stays strong against most chemicals. This makes it safe for melting metals. Gold or silver refining needs this safety. Chemical analysis labs use these crucibles too. Samples stay pure inside them.

Mechanical strength matters. Alumina ceramic is very hard. It does not break easily under stress. People move crucibles when they are hot. The material handles this physical load. Thermal shock resistance is also key. Going from hot to cold quickly cracks weak materials. Alumina handles these rapid changes better than many others.

Many industries need these properties. Metallurgy uses alumina crucibles daily. They melt and cast different metals. Laboratories rely on them for precise experiments. Material science research depends on them. Ceramic powder production uses alumina boats. Samples travel through kilns inside them. Jewelers use small crucibles for precious metals. Semiconductor manufacturing needs ultra-pure alumina containers. They grow crystals or process wafers. The high purity prevents contamination.

5 FAQs of Alumina Al2o3 Ceramic Crucible/boat Container Ceramic Products

Here are 5 common questions about Alumina (Al2O3) Ceramic Crucible/Boat Containers:

What material is this crucible made from?
This crucible is made from alumina ceramic. Alumina is aluminum oxide. It’s a very hard material. It handles extreme heat well. It resists chemicals strongly. This makes it perfect for tough lab or factory work.

How hot can this crucible safely get?
These crucibles handle very high temperatures. They work fine up to 1700°C (3092°F). Some special grades go even higher. Check the specific product details. Always stay below the maximum rated temperature. Exceeding it risks damage.

What chemicals won’t attack this alumina crucible?
Alumina ceramic resists many chemicals. It handles strong acids well. It handles strong bases well. Common examples are nitric acid, sulfuric acid, and sodium hydroxide. Molten salts generally don’t harm it. Avoid hydrofluoric acid and phosphoric acid. They attack alumina.

Can the crucible handle sudden temperature changes?
Alumina ceramic is strong but brittle. It doesn’t love quick temperature swings. This is called thermal shock. Avoid heating or cooling it too fast. Sudden changes can cause cracks. Heat it slowly. Cool it slowly. This practice extends its life.

How do I clean the crucible after use?
Cleaning depends on what was inside. Remove loose residue first. Soak the crucible in hot water. Use a suitable acid solution for stubborn deposits. Hydrochloric acid often works. Avoid harsh abrasives. They scratch the surface. Rinse very well with pure water after cleaning. Let it dry completely before reuse.
