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 High Al203 corundum mullite saggar crucible kiln shelves refractory alumina ceramic sagger tray for furnace

This High Al2O3 corundum mullite saggar crucible offers serious performance for demanding furnace work. It’s built tough. The core material blends high-purity corundum with mullite. Alumina content hits over 85%. This mix delivers critical high-temperature stability.

These saggars handle extreme heat easily. Maximum working temperature reaches 1600-1700°C. They resist thermal shock well. Sudden temperature changes cause less cracking. This toughness means longer life. You get more cycles before replacement.

Low porosity is a major plus. The dense structure minimizes gas passage. This protects sensitive furnace contents. Contamination risk drops significantly. Furnace atmosphere stays cleaner. Your materials stay purer.

Mechanical strength is high. These saggars support heavy loads. They resist deformation under heat. Kiln shelves stay stable. Crucibles maintain their shape. This ensures consistent processing batch after batch.

Chemical resistance is strong. The material withstands aggressive furnace environments. It fights off acidic or basic fluxes. Material degradation slows down. This further extends usable life.

These saggars are perfect for critical high-heat tasks. They excel in sintering advanced ceramics. Firing electronic components is a common use. Lithium battery material production relies on them. Jewelry casting and metal heat treatment benefit too. They are essential kiln furniture.

Applications of High Al203 corundum mullite saggar crucible kiln shelves refractory alumina ceramic sagger tray for furnace

These high alumina products offer serious performance for demanding furnace work. Saggars crucibles hold items during high temperature firing. They protect delicate pieces from direct flame and fumes. Kiln shelves provide sturdy support for heavy loads. Refractory trays organize materials efficiently inside the furnace. All these components withstand extreme heat, often over 1600°C. They resist thermal shock from rapid heating and cooling cycles. This prevents cracking and warping during repeated use. Their dense structure also fights chemical attack from fluxes and glazes.

Ceramic manufacturers heavily rely on them. Saggars crucibles safely fire technical ceramics like zirconia or advanced oxides. Kiln shelves carry large batches of tiles or sanitaryware. The trays neatly hold electronic components during sintering. Metallurgical processes use these alumina parts too. Crucibles contain molten metals or alloys for testing. Shelves support metal parts during heat treatment. Trays hold catalyst materials in calcination furnaces.

The key is the high Al2O3 content combined with mullite. This mix delivers exceptional refractoriness. It means the material stays strong and stable under intense heat. Corundum adds hardness and erosion resistance. Mullite improves thermal shock performance. The result is a long service life. Users get fewer replacements and less furnace downtime. These products maintain dimensional accuracy. They don’t slump or distort under load at high temperatures. This ensures consistent firing results batch after batch. Their inert nature prevents contamination. Fired materials keep their purity and intended properties. These alumina ceramics handle harsh conditions reliably. They are vital for efficient, high-quality industrial heating.

5 FAQs of High Al203 corundum mullite saggar crucible kiln shelves refractory alumina ceramic sagger tray for furnace

Here are 5 common questions about High Al2O3 Corundum Mullite Saggar Crucibles:

What is this saggar crucible made of? It uses a special mix. The main part is alumina (Al2O3). The amount is very high. This gives great heat resistance. It also contains mullite. Mullite adds strength. It helps the crucible handle big temperature changes. This mix is much better than basic clay.

How hot can I safely use this saggar? These saggars work well under extreme heat. They handle temperatures up to 1650°C (around 3000°F). This is hot enough for most advanced ceramics and metals. Check the exact grade first. Some specific types might go higher or lower.

Can it take sudden temperature changes? Yes, thermal shock resistance is a key strength. The corundum-mullite material expands slowly when heated. It contracts slowly when cooled. This means less stress inside the material. You can heat it up fast. You can cool it down fast. It resists cracking much better than cheaper options.

How long will one last? The lifespan depends heavily on use. The main factors are the peak temperature you use. The speed of your heating and cooling cycles matters. How you load and unload the crucible is important. Proper handling avoids chips and cracks. Used correctly, it lasts many more cycles than basic saggars. It saves money over time.

Can I clean and reuse it? Yes, reuse is expected. Let the crucible cool completely after firing. Remove any leftover material inside carefully. Use tools that won’t scratch the surface. Avoid heavy impacts. Inspect it for cracks or serious damage before using it again. A good crucible withstands repeated cleaning and firing cycles.
