Specification of BIG Size 99% Al2O3/alumina Ceramic Crucibles /BIG CRUCIBLE

These BIG CRUCIBLES are large alumina ceramic crucibles. They are made from 99% pure Al2O3. This high purity is key. It gives the crucibles excellent performance. They handle very high temperatures well. You can use them up to 1750°C. This is important for melting metals or processing chemicals. They resist sudden temperature changes. This means less cracking from thermal shock.

Chemical resistance is another big advantage. The 99% alumina fights off acids and alkalis. This is crucial for harsh lab or industrial settings. The material won’t react with your melts. Your results stay pure. These crucibles are very dense. This density stops liquids from soaking in. Your melts stay contained. Cleaning is easier too.

These crucibles are physically strong. They resist wear and abrasion. They last longer than cheaper options. Their big size holds more material. You need fewer runs for large batches. This saves time and effort. The crucibles maintain their shape under heat. This ensures consistent results every time.

They are perfect for demanding jobs. Use them for melting precious metals. Use them for sintering advanced ceramics. Use them for high-temperature chemical analysis. Their reliability matters. You need equipment you trust. These crucibles deliver consistent performance. They withstand tough conditions. Their large capacity handles significant volumes. This makes them essential for serious production or research. Choose them for heavy-duty applications.

5 FAQs of BIG Size 99% Al2O3/alumina Ceramic Crucibles /BIG CRUCIBLE

BIG Size 99% Alumina Ceramic Crucible FAQ

What sizes do your BIG crucibles come in?
We offer large sizes. Common capacities are 500ml, 1000ml, and 2000ml. Larger custom sizes are possible. Check our catalog for exact dimensions. We focus on crucibles bigger than standard lab sizes.

How hot can I heat these big crucibles?
They handle very high temperatures. Maximum continuous use is 1650°C (3002°F). Short peaks to 1750°C (3182°F) are okay. This suits most metal melting and high-temperature processing. Their purity helps them resist heat well.

Will chemicals damage the crucible?
These crucibles resist many chemicals. They are great against strong acids and bases. They are also good with molten salts. Avoid hydrofluoric acid and strong alkalis at high temperatures. Their dense structure stops most corrosion.

Are BIG crucibles fragile?
Alumina ceramic is hard but brittle. Handle them carefully. Avoid impacts or sudden temperature changes. Don’t drop them. Thermal shock resistance is good, but fast heating or cooling can cause cracks. Use proper tools for moving hot crucibles.

Why choose a BIG alumina crucible over a smaller one?
You need a BIG crucible for larger batches. Melting more metal or processing more material requires bigger capacity. Our large crucibles maintain the same high purity and temperature resistance as smaller ones. They offer the same quality just scaled up.
