High-Temperature Alumina Crucible for Gold Melting

Pure 99% Al ₂ O Six Construction

This crucible is made from 99% pure alumina (Al two O ₃). The high pureness gives it outstanding resistance to chain reactions. It stays stable even when touching liquified gold or other rare-earth elements. You can trust it not to pollute your thaw.

Stands Up To Extreme Heat

The crucible works securely at temperatures in between 1500 ° C and 1800 ° C . This variety covers all common gold melting demands. It deals with duplicated heating and cooling without splitting or flawing. The product keeps its form and toughness under extreme thermal stress.

Constructed for Long Service Life

Many thanks to its dense framework and high pureness, this crucible lasts longer than typical ceramic alternatives. It resists thermal shock, disintegration, and steel infiltration. You obtain constant efficiency over many melting cycles. Much less constant replacement suggests lower operating costs.

Ideal Sizes And Shape

Made as a cup-style crucible, it offers easy pouring and efficient warm transfer. The smooth inner surface area aids thaw gold flow cleanly. Criterion sizes fit most induction and gas-fired heaters used in jewelry workshops and small factories.

Safe and Dependable Efficiency

Gold refiners and jewelry experts rely upon this crucible for tidy, contamination-free outcomes. It does not launch gases or pollutants throughout melting. That guarantees your end product fulfills high quality standards. The crucible likewise cools equally, lowering the danger of sudden damage.

Use this high-temperature alumina crucible whenever you need trustworthy efficiency for melting gold, silver, platinum, or various other rare-earth elements. Its combination of purity, stamina, and thermal security makes it a smart option for specialists that value precision and resilience.

Applications of 1500-1800C High Temperature 99 Al2o3 Alumina Ceramic crucible Cup For Melting Gold

High-Temperature Alumina Crucible for Gold Melting

Developed for Extreme Heat

This crucible is made from 99% pure alumina (Al ₂ O THREE) ceramic. It handles temperatures from 1500 ° C to 1800 ° C without fracturing or warping. Gold melts around 1064 ° C, so this cup uses a strong safety and security margin for repeated use in high-heat atmospheres.

Perfect for Rare-earth Element Job

Gold refiners, jewelers, and lab service technicians rely upon this crucible for tidy, constant melting. The high purity of the alumina avoids undesirable responses with liquified gold. No discoloration. No contamination. Just pure steel every single time.

Durable and Lasting

Unlike graphite or clay-graphite crucibles, this alumina version resists chemical wear and thermal shock. It will not flake or lose particles right into your thaw. That implies less pollutants and less waste. You get even more usable gold from each batch.

Tidy and Easy to Utilize

The smooth inner surface lets molten gold put out easily. Residue sticks much less, so clean-up takes much less time. After cooling, you can reject leftover little bits without damaging the cup. This saves effort and keeps your workspace clean.

Fits Common Furnaces

Developed to collaborate with basic induction, gas, or electrical melting heaters. Its sizes and shape suit normal setups utilized in little factories and jewelry studios. You will not require special devices to start utilizing it right away.

This crucible gives you integrity where warm and pureness issue the majority of. Whether you’re recouping gold from scrap or casting great precious jewelry, it executes under stress– set after set.

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

Common Questions About Our High-Temperature Alumina Crucible

What is this crucible made of?

This crucible is made from 99% pure alumina (Al₂O₃). It can handle very high temperatures up to 1800°C. The material is strong, chemically stable, and resists wear. That makes it safe for melting gold and other precious metals.

Can I use it to melt gold?

Yes. This crucible works well for melting gold. Gold melts around 1064°C, which is far below the crucible’s maximum temperature. The high purity of alumina prevents unwanted reactions with molten gold. Your metal stays clean and uncontaminated.

Why choose alumina over other materials?

Alumina has excellent heat resistance and does not crack easily under thermal stress. Unlike graphite or clay-graphite crucibles, pure alumina will not add carbon or impurities to your melt. It also lasts longer when used correctly, giving you better value over time.

How do I heat the crucible safely?

Always preheat the crucible slowly before reaching full melting temperature. Sudden heating can cause cracks. Place it in a furnace or kiln and raise the temperature gradually. Avoid direct flame contact if possible. Let it cool down naturally after use—do not quench it in water.

How long will the crucible last?

Lifespan depends on how often you use it and how you handle it. With proper preheating, gentle handling, and clean melting practices, one crucible can be used many times. Avoid dropping it or exposing it to rapid temperature changes. Store it in a dry place when not in use to prevent moisture damage.
