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 temperature al2o3 ceramic corundum boat crucible

This heat Al2O3 ceramic corundum watercraft crucible manages severe heat. It’s made from nearly pure alumina (Al2O3). This material is extremely solid. It stands up to really high temperatures well. These crucibles function progressively up to 1700 ° C (3092 ° F). They can manage short bursts even hotter.

The structure is thick. This suggests low porosity. Impurities don’t seep right into the material quickly. Your samples stay pure. The ceramic additionally fights chemical strike. Acids and bases do not harm it a lot. Thermal shock resistance is great as well. It deals with quick temperature changes without breaking.

Standard dimensions prevail. You locate boats like 50mm, 70mm, 100mm lengthy. Width and depth vary based on the design. Wall surface density is generally around 3mm to 5mm. This balances strength and warmth transfer. Custom-made sizes are possible also.

These crucibles are perfect for labs and sector. Use them for sintering ceramics or metals. They help heat dealing with small parts. Annealing procedures require them. Calcining powders fits well. High pureness melting jobs utilize them often. They prevail in tube furnaces.

Handling calls for care. Stay clear of abrupt impacts. Don’t drop them. Thermal biking should be steady whenever feasible. Tidy them meticulously after use. Correct handling makes them last longer. They are breakable like many porcelains.

Applications of High temperature al2o3 ceramic corundum boat crucible

Heat Al ₂ O five ceramic diamond boat crucibles take care of severe warm extremely well. They are vital devices across many requiring sectors. Semiconductor manufacturing counts greatly on these crucibles. They lug silicon wafers safely through diffusion and oxidation heaters. The pure alumina material stops contamination of sensitive wafers. Product researchers use these watercrafts continuously. They hold examples firmly during sintering experiments. They hold up against repeated thermal biking in tube heaters. Warmth therapy processes require trusted crucibles. These diamond boats are best for annealing metals. They are likewise utilized for tempering glass components. Their security prevents responses with warm materials. Crystal growth calls for specific, inert atmospheres. These alumina watercrafts provide that stable base. They are excellent for vapor transportation crystal development techniques. Their smooth surface areas allow simple crystal removal later on. Analytical chemistry laboratories rely on these crucibles. They serve as example owners in thermal gravimetric evaluation. They also function well in important analysis tools. The crucibles maintain honesty under constant high heat. Chemical vapor deposition processes utilize these watercrafts too. They transport substratums right into high-temperature response zones. The alumina resists attack from numerous hostile chemicals. Their design is straightforward and functional. This allows simple loading and unloading of examples or products. Their long life saves money over time. Changing breakable containers becomes unnecessary. These crucibles offer regular efficiency set after set. They are a basic tool for high-temperature work.

5 FAQs of High temperature al2o3 ceramic corundum boat crucible

What’s the highest temperature this crucible handles?
It withstands 1750°C continuously. Short bursts reach 1800°C. Going higher risks damage. Stick to 1750°C for safety.

Can it handle sudden temperature changes?
Yes, but carefully. Heating too fast cracks it. Heat it slowly. Cool it slowly too. Avoid drafts on hot crucibles. Thermal shock is the main risk.

What chemicals won’t damage it?
It resists most acids and alkalis well. Hydrofluoric acid and strong phosphoric acid attack it. Molten alkalis and some metal oxides damage it too. Check chemical compatibility lists first.

How do I clean it after use?
Remove cooled residue mechanically first. Use a soft tool. Avoid metal scrapers. Soak in suitable acid or solvent if needed. Rinse very well with water. Dry it completely before reuse. Never thermal shock it cleaning.

How long does one crucible last?
Lifespan varies a lot. It depends on temperatures used, thermal cycling speed, chemicals present, and handling care. Gentle use gives many runs. Rough use, extreme temperatures, or harsh chemicals shorten life fast. Expect gradual wear over time.
