Specifications of High temperature Al2O3 Crucible alumina corundum ceramic boat for laboratory furnace

This alumina ceramic boat is a high-temperature crucible made from Al2O3. It’s created for demanding lab heater use. The product is alumina corundum. This ceramic offers extraordinary resistance to severe heat. It handles temperature levels approximately 1800 ° C dependably. This makes it appropriate for sintering, annealing, and calcination processes.

The crucible boasts high purity. Typical purity levels are 99% Al2O3 or higher. This pureness decreases contamination dangers. It guarantees your examples stay unaffected by the crucible product throughout home heating. Alumina ceramic is chemically inert. It stands up to attack from many acids, bases, and molten salts. This inertness is vital for constant experimental outcomes.

These watercrafts are extremely strong mechanically. They withstand thermal shock well. This implies they can deal with fast temperature modifications without splitting. The dense framework stops gases from penetrating. This shields delicate products inside the heating system environment. The surface area is smooth and difficult. This prevents sample sticking and makes cleansing easier.

Alumina ceramic watercrafts work well for example holders. They are perfect for powder handling. They offer reliably in tube heaters and smother heaters. Common applications consist of catalyst screening, material research, and ceramic handling. They are available in various dimensions. Criterion dimensions fit most laboratory heaters. Personalized sizes are often readily available as well. The shape is simple. It permits very easy loading and discharging of examples. Alumina crucibles last a long period of time. Their longevity gives excellent worth. They exceed numerous metal choices at really heats. They supply a steady system for important lab job.

Applications of High temperature Al2O3 Crucible alumina corundum ceramic boat for laboratory furnace

These alumina diamond ceramic boats are essential devices for high-temperature lab work. They are made from pure light weight aluminum oxide (Al2O3). This material manages severe warm incredibly well. Lab heaters get to extremely heats. These watercrafts stand up to brutal heater problems conveniently. They continue to be secure and maintain their shape. This is necessary for trusted results.

Researchers use these crucible watercrafts continuously. They are best for sintering ceramic powders. The boats hold examples during the home heating process. They ensure also warmth circulation. This helps products bond appropriately. Metallurgists likewise rely upon them. Thawing tiny metal samples requires a steady container. These alumina watercrafts supply that stability. They do not respond with molten metals. This maintains experiments pure.

Handling delicate samples is one more crucial usage. The boats bring materials into the heating system safely. They secure samples throughout firing. Scientist research crystal development inside them. Warm treatment processes usually occur within these boats. Their chemical inertness is a significant benefit. They resist attack from acids, bases, and changes. This prevents contamination. Samples stay unchanged by the container itself.

Physical toughness matters substantially. Alumina diamond is extremely difficult. It withstands wear and thermal shock. Unexpected temperature level modifications can break weaker materials. These boats take care of rapid heating and cooling cycles well. This sturdiness indicates they last a long period of time. Labs save cash by reducing substitute expenses. Their smooth surface is very easy to tidy. Residue doesn’t stick firmly. Reuse is basic and risk-free.

5 FAQs of High temperature Al2O3 Crucible alumina corundum ceramic boat for laboratory furnace

High-Temperature Al2O3 Crucible Alumina Corundum Ceramic Boat FAQ

What’s the highest temperature this crucible handles?
This alumina crucible works reliably up to 1750°C (3182°F). It withstands continuous use at these extreme temperatures. It’s designed for demanding lab furnace applications. Its pure alumina composition provides excellent stability.

Can it hold molten metals?
Yes. This crucible resists attack from most molten metals. It works well with gold, silver, copper, and many alloys. Avoid highly reactive metals like titanium or zirconium. These can damage the alumina over time. Check chemical compatibility for your specific metal.

Will it crack from sudden temperature changes?
This crucible handles thermal shock better than many ceramics. Alumina corundum has good thermal shock resistance. Avoid very rapid heating or cooling cycles. Always follow recommended furnace ramp rates. Pre-heating the crucible slowly is best practice.

How do I clean it after use?
Cleaning is usually straightforward. Let the crucible cool completely. Remove loose residue mechanically. Use a soft brush or tool. For stubborn material, soak it in a suitable acid or solvent. Avoid harsh abrasives. They can scratch the surface. Rinse thoroughly with water afterward.

How long will one crucible last?
Crucible lifespan depends heavily on usage. Factors include maximum temperature, thermal cycles, and chemicals contacted. Under normal lab conditions, expect good performance for multiple uses. Inspect it regularly for cracks or erosion. Replace it if you see significant damage. Proper handling extends its life.
