Applications of High-Purity 99% Alumina Ceramic Bowl Crucible Cup for Gold Melting

These alumina ceramic bowl crucibles are made for melting gold. They are tough and handle very high heat well. People use them a lot in jewelry making and places that work with precious metals. The material is over 99% pure aluminum oxide. This purity is key. It means the crucible won’t add anything bad to your gold melt. You get clean, pure gold every time. The ceramic also resists chemicals. Acids and bases won’t damage it easily. This keeps the crucible strong for many uses. It also means your melted gold stays pure. No unwanted stuff gets in.

The crucible handles temperatures over 1700°C easily. This is much hotter than needed for melting gold. You don’t have to worry about the crucible cracking or breaking from the heat. Gold melts around 1060°C. This crucible is built for much more. It gives you a big safety margin. You can heat it up fast or cool it down slow. It stays strong. This makes your melting process reliable.

These crucibles are perfect for small amounts of gold. Jewelers use them for casting rings or pendants. Hobbyists use them for refining scrap gold. Labs use them for testing gold purity. The bowl shape makes pouring easy. You get smooth casts. The ceramic doesn’t stick to the molten gold. Your gold comes out clean. You lose less metal. You save money. Cleaning is simple too. Just brush it out after it cools. No residue is left behind.

Handling needs care. These are ceramic. They can break if dropped hard. Always use proper tongs. Let the crucible cool down before cleaning. Avoid sudden temperature shocks. Moving it from very hot to cold too fast can cause stress. Handle it gently. Store it safely when not in use.

5 FAQs of High-Purity 99% Alumina Ceramic Bowl Crucible Cup for Gold Melting

What’s the maximum temperature this alumina crucible can handle?
This crucible works fine up to 1700°C. It handles typical gold melting temperatures easily. The crucible stays stable under intense heat. It won’t crack or warp like cheaper materials might. This makes it reliable for repeated gold melting cycles.

Is the 99% purity important?
Yes, the 99% purity is critical. Lower purity alumina might have impurities. These impurities could contaminate your molten gold. High purity means the crucible itself won’t add unwanted elements. You get purer gold after melting.

Will molten gold stick to the crucible?
No, molten gold won’t stick. The alumina surface is very smooth. It’s also chemically inert. This means gold doesn’t react with it or bond to it. Your melted gold pours out cleanly. You won’t lose valuable metal stuck inside.

Is the crucible fragile?
Handle it with reasonable care. Alumina ceramic is strong. It resists thermal shock well. Avoid dropping it hard or hitting it against metal surfaces. Don’t heat it up or cool it down too fast. Following these steps ensures it lasts a long time.

How do I clean the crucible after use?
Cleaning is usually simple. Let the crucible cool down completely after melting. Any leftover gold slag brushes off easily most times. For tougher residue, a quick soak in diluted acid helps. Rinse it well with water afterwards. It dries ready for the next melt.
