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 Custom Large-Diameter Alumina Ceramic Corundum Tube Alumina Ceramic Crucible High Durability And Thermal Conductivity

Custom large-diameter alumina ceramic tubes solve tough high-temperature problems. These corundum tubes handle extreme heat and harsh chemicals easily. We make them in diameters from 1mm up to 100mm. Wall thickness ranges from 0.5mm to 10mm. Lengths reach 3000mm. The material is pure. It’s 99.5% alumina (Al2O3). This purity creates a strong corundum crystal structure. That structure means excellent durability.

Our matching alumina ceramic crucibles are just as tough. They come in many shapes. Common types are boat, cylindrical, and conical crucibles. Sizes vary greatly. We offer small lab crucibles and large industrial ones. Custom sizes are available. Crucible walls are thick enough for strength. They resist thermal shock well. Moving them from hot to cold won’t crack them easily.

Performance is key. These alumina products withstand temperatures up to 1800°C. They have low thermal expansion. Heat doesn’t make them grow much. This prevents cracking. Thermal conductivity is good. It’s about 30 W/m·K. Heat moves through them efficiently. Electrical insulation is very high. They won’t conduct electricity. Chemical resistance is outstanding. Acids, alkalis, and molten metals don’t damage them. Mechanical strength is high. They resist wear and abrasion. Surface finish is smooth. Typical roughness (Ra) is below 0.2μm. Density is high too. It’s around 3.9 g/cm³. This means less porosity. Leakage is minimized.

People use these tubes and crucibles in demanding places. Semiconductor processing needs them. Heat treatment furnaces rely on them. Metallurgy uses them for melting and casting. Chemical analysis labs require them. Powder metallurgy processes utilize them. Anywhere heat and corrosion are problems, alumina ceramics help. We manufacture using advanced methods. Isostatic pressing and extrusion are common. Sintering at high temperatures makes them solid. Quality control is strict. Every piece meets exact standards.

Applications of Custom Large-Diameter Alumina Ceramic Corundum Tube Alumina Ceramic Crucible High Durability And Thermal Conductivity

Large custom alumina ceramic tubes handle tough jobs. Their big size fits special equipment needs. Factories use them for moving hot materials in kilns. They withstand extreme heat without cracking. Labs rely on them for high-temperature experiments. Their smooth surface keeps things clean. They resist chemicals well. This makes them safe for harsh processes. Heat moves through them fast. This helps control temperatures precisely. Furnace linings often use these tubes. Semiconductor plants need their purity.

Alumina ceramic crucibles are built to last. They hold molten metals safely. Foundries use them daily for casting. They cope with rapid heating and cooling. Thermal shock won’t break them easily. Their strength handles heavy loads. Chemists heat aggressive substances inside them. They don’t react with most chemicals. This keeps experiments accurate. These crucibles work in material research. They test new alloys under fire. Their thermal conductivity spreads heat evenly. This prevents hot spots.

Both tubes and crucibles offer high durability. They last much longer than metal options. This saves money on replacements. Their thermal conductivity improves efficiency. Processes need less energy over time. They perform reliably in demanding places. Steel mills, glass factories, and labs trust them. Custom sizes fit exact machine requirements. Their resistance to wear reduces downtime. Handling is safer because they stay cool outside. They maintain performance cycle after cycle. Choosing the right alumina grade matters for each job.

5 FAQs of Custom Large-Diameter Alumina Ceramic Corundum Tube Alumina Ceramic Crucible High Durability And Thermal Conductivity

What sizes do your custom alumina ceramic tubes come in?
We make large-diameter tubes to your exact needs. Tell us the inner diameter, outer diameter, and length you require. We handle complex sizes other suppliers might refuse. Our focus is fitting your specific application perfectly.

How durable are these alumina ceramic crucibles?
They are extremely tough. The alumina ceramic material resists breaking under high heat and physical shock. This toughness means fewer replacements. You save money long-term. They withstand harsh chemicals too, ideal for labs and foundries.

Why is thermal conductivity important in these tubes?
Good heat transfer matters. Our tubes move heat efficiently. This avoids hot spots that can damage materials inside. Consistent heating or cooling happens faster. That means better process control and results in furnaces or reactors.

Can I get custom shapes beyond standard tubes and crucibles?
Yes. We specialize in custom ceramic parts. Send us your drawings or specifications. We produce complex shapes like boats, trays, or special holders. The alumina ceramic works for unique designs needing high heat resistance.

What industries use these alumina ceramic products most?
Many industries rely on them. Semiconductor manufacturing uses our tubes for high-purity processes. Metallurgy uses crucibles for melting metals. Research labs need them for experiments under extreme heat. Anywhere high temperature and chemical resistance are critical, they perform.
