Specification of Al2O3 Aluminum Oxide Ceramic Crucible Alumina Rod for Laboratory Use for Melting Gold & Silver Welding Services Included

This Al2O3 aluminum oxide ceramic crucible and matching alumina rod are made for serious lab work. They handle intense heat needed for melting gold and silver. The material is nearly pure aluminum oxide, over 99% Al2O3. This purity gives excellent performance.

These crucibles resist very high temperatures. They work fine up to 1700°C (3100°F) consistently. Sudden temperature changes won’t crack them easily. This thermal shock resistance is crucial for melting cycles. The crucible shape is designed for efficient melting. It holds metal securely. The alumina rod is strong and heat resistant too. It’s perfect for stirring molten metal safely.

The material is chemically inert. It won’t react with molten gold or silver. This keeps your precious metals pure. Contamination is not a problem. The surface is very smooth inside. This helps prevent material sticking after pouring. Cleaning is much simpler.

These items are incredibly tough. They resist wear and abrasion extremely well. They last much longer than cheaper alternatives. You save money over time. They handle the physical stress of repeated use. Breaking is unlikely.

We include professional welding services. If your crucible or rod gets damaged, we can fix it. This service extends the life of your investment significantly. Get back to work fast. Our welding uses compatible high-purity alumina materials. The repair is strong and reliable.

5 FAQs of Al2O3 Aluminum Oxide Ceramic Crucible Alumina Rod for Laboratory Use for Melting Gold & Silver Welding Services Included

What are Al2O3 crucibles made of?
They are made from aluminum oxide ceramic. This material is very pure. It’s also called alumina. This gives the crucible its special properties.

How hot can these crucibles get?
These crucibles handle extreme heat well. They work fine up to 1700°C (3092°F). This is much hotter than needed for melting gold or silver. They resist sudden temperature changes too. Taking them from hot to cold quickly usually doesn’t crack them.

Why use alumina for melting gold and silver?
Alumina crucibles won’t react with molten gold or silver. They keep your metal pure. Other materials might contaminate your melt. Plus, alumina is very hard. It resists wear from stirring or pouring. This means your results stay consistent.

How long do these crucibles last?
They last much longer than cheaper graphite or clay crucibles. Alumina is very tough. It resists chemical attack and physical wear. You get more melts from one crucible. This saves money over time. Handle them carefully though. Dropping them can still cause breakage.

What welding service is included?
We offer welding on alumina rods. This service uses the same high-purity Al2O3 ceramic. It creates strong, heat-resistant joints. This is useful for custom lab setups or repairs. Tell us what you need welded. We can handle specific shapes or parts.
