Applications of 1500-1800C High Temperature 99 Al2o3 Alumina Ceramic Corundum Crucible For Melting Gold

This crucible handles extreme heat. It’s made from 99% pure alumina ceramic. This material is very dense and strong. It withstands temperatures from 1500°C to 1800°C. This is perfect for melting gold. Gold melts around 1064°C. This crucible works well above that point.

Alumina ceramic resists thermal shock. Sudden temperature changes won’t crack it easily. This is crucial for repeated melting and cooling cycles. It also resists chemical attack. Molten gold won’t stick to it or react with it. Your melt stays pure. You avoid contamination. This is vital for quality results.

This crucible outperforms graphite or clay. Graphite can burn away over time. It also adds carbon to your melt. Clay crucibles often crack sooner. They might add impurities too. The alumina crucible lasts longer. It saves you money on replacements.

Gold workers need this tool. Jewelers use it for casting new pieces. Refineries use it to process gold scrap or ore. Recyclers melt down old jewelry or electronics. Labs use it for precise gold experiments. It handles small amounts for testing. It also handles larger batches for production.

The high purity alumina ensures no unwanted elements enter your gold. You get consistent results every melt. The crucible maintains its shape under intense heat. This provides reliable performance. Its smooth surface makes pouring easy. Cleaning is simple after use. It offers a dependable solution for serious gold melting tasks.

5 FAQs of 1500-1800C High Temperature 99 Al2o3 Alumina Ceramic Corundum Crucible For Melting Gold

What temperature can this crucible handle?
This alumina ceramic crucible withstands extreme heat. It handles temperatures up to 1800°C (3272°F) easily. That’s hot enough for melting gold, silver, copper, and similar metals. It doesn’t crack or melt under normal use.

How pure is the alumina material?
It’s made from 99% pure Al2O3 alumina. This high purity is essential. Impurities weaken the crucible. They can also contaminate your melt. Pure alumina ensures cleaner results.

Will this crucible crack easily?
It resists thermal shock well. But you must preheat it correctly. Never put a cold crucible into a hot furnace. Heat it slowly first. Avoid sudden temperature drops. Handle it carefully. It lasts many melts if used right.

Do I need to prepare it before first use?
Yes. Always preheat a new crucible slowly. Heat it gradually to 600°C (1112°F). Hold that temperature for about 30 minutes. This step burns off any tiny residues. It makes the crucible stronger for melting.

What sizes are available?
Common sizes hold 10ml, 20ml, 50ml, 100ml, and larger volumes. Choose the size matching your metal amount. A too-large crucible wastes energy. A too-small one risks overflow. Measure your metal charge first. Pick the right crucible size.
