Specifications of Large Size High Hardness Aluminium Oxide Al2O3 Refractory Ceramic Crucible Large Capacity Alumina Ceramic Cylinder

This large ceramic crucible handles demanding high-temperature tasks. It’s made from aluminium oxide (Al2O3). The Al2O3 content is very high. This gives exceptional hardness. The material resists wear extremely well. The crucible shape is a sturdy cylinder. This design offers large capacity. You can melt significant amounts of material inside. The size is substantial. It suits industrial foundries and busy laboratories.

The ceramic is refractory grade. It withstands intense heat. Operating temperatures reach over 1700°C. Thermal shock resistance is excellent. The crucible won’t crack easily during rapid heating or cooling cycles. This reliability matters for repeated use. Chemical stability is another key feature. It resists attack from many molten metals and slags. Acids and alkalis generally don’t affect it. This ensures material purity.

The structure is dense. Low porosity prevents leaks. Contamination risks are minimized. The surface is smooth. This makes cleaning simpler between melts. Mechanical strength is impressive. The crucible bears heavy loads without breaking. Long service life reduces replacement costs. It’s proven in applications like metal casting, glass work, and chemical analysis. Consistent performance is guaranteed.

Durability comes from the high Al2O3 purity. Manufacturing uses advanced sintering. This creates a uniform, tough microstructure. The crucible handles thermal cycling day after day. It’s a robust tool for harsh environments. Large batches are processed efficiently. Users value its dependable nature under fire.

Applications of Large Size High Hardness Aluminium Oxide Al2O3 Refractory Ceramic Crucible Large Capacity Alumina Ceramic Cylinder

Large alumina ceramic crucibles handle extreme heat and harsh conditions. Aluminium oxide (Al2O3) gives them exceptional hardness. This hardness fights wear and tear. Their large size holds significant material volumes. This big capacity suits demanding industrial processes.

These crucibles excel in melting metals. Foundries and metal producers use them constantly. They handle molten iron, steel, copper alloys, and precious metals like platinum. The high purity alumina prevents contamination. This ensures the final metal quality stays excellent.

Crystal growth labs rely on these crucibles. The material purity is critical here. Impurities ruin crystal structures. Alumina keeps the melt clean. The crucible withstands the long, high-temperature cycles needed for crystal formation. Stability matters greatly.

Chemical processing plants use large alumina cylinders. They contain aggressive chemical reactions. Alumina resists strong acids and alkalis well. This chemical inertness protects the process integrity. It also protects the crucible itself from attack.

High-temperature testing labs need durable containers. These alumina crucibles provide that. Researchers subject materials to intense heat. The crucible must survive unchanged. It offers a reliable platform for experiments.

Thermal shock resistance is a key benefit. Crucibles heat up fast and cool down fast. Sudden temperature changes crack weak materials. High-purity alumina handles these shocks better. This toughness extends the crucible’s working life.

Long service life reduces replacement costs. Downtime for swapping crucibles decreases. Operations run smoother. The initial investment pays off over time. Toughness equals cost efficiency.

Industrial kilns and furnaces demand robust parts. Large alumina cylinders fit this need. They serve as furnace liners, supports, and tubes. They endure constant exposure to intense heat. Mechanical strength prevents failure under load.

These crucibles suit precious metal recovery too. Recyclers process scrap gold and silver. A chemically inert container is essential. Alumina ensures no valuable metal is lost. It also withstands the required processing temperatures reliably.

5 FAQs of Large Size High Hardness Aluminium Oxide Al2O3 Refractory Ceramic Crucible Large Capacity Alumina Ceramic Cylinder

What material is this crucible made from?
This crucible uses pure aluminium oxide. We call it Al2O3 ceramic. It’s high purity. This gives the crucible its strength. It also makes it very hard. The material resists high temperatures well. It handles chemical reactions too. This is important for melting metals. It’s safe for labs and industry.

How hot can this crucible get?
This large crucible handles extreme heat. Its maximum working temperature is 1650°C. It can reach 1700°C for short periods. This is much hotter than many metals melt. The material stays stable. It doesn’t soften or warp easily. It’s built for tough jobs.

Is it really strong and hard?
Yes. High hardness is a key feature. The Al2O3 ceramic is very dense. This makes it incredibly scratch resistant. It stands up to rough handling. Abrasion won’t wear it down fast. It handles sudden temperature changes without breaking. This toughness means it lasts longer.

How big is it?
This is a large capacity crucible. Its inner diameter is 100mm. The height is 150mm. The wall is thick, about 10mm. This gives it strength for heavy loads. You can melt more material at once. It saves time. It fits standard furnace setups.

How do I care for it?
Handle it carefully. Avoid sharp impacts. Don’t heat it too fast. Let it cool down slowly after use. Clean it with mild acid or sandblasting. Avoid thermal shock. Sudden cold on hot crucible is bad. Check for cracks before each use. Proper care makes it last years.
