Overview of Corundum Crucible

Corundum crucibles, made from alumina (Al₂O₃), are highly valued for their exceptional thermal resistance and chemical stability. These crucibles are ideal for high-temperature applications, such as melting and annealing processes in laboratories and industrial settings. Corundum crucibles can withstand temperatures up to 1800°C and are resistant to most chemical reagents, making them indispensable in various scientific and manufacturing operations.

Features of Corundum Crucible

High Thermal Resistance: Can withstand temperatures up to 1800°C without degrading.

Chemical Stability: Resistant to most acids and alkalis, ensuring minimal contamination during experiments or production.

Durability: Extremely durable and long-lasting, even under harsh conditions.

Non-Reactive: Does not react with the materials being processed, preserving sample purity.

Versatility: Suitable for a wide range of applications including melting metals, glass, and ceramics.

Precision Engineering: Manufactured to tight tolerances for consistent performance and reliability.

Specification of 1500-1800C high temperature 99 al2o3 alumina ceramic corundum crucible for melting gold

This alumina ceramic crucible manages severe heat. It endures temperature levels from 1500 ° C to 1800 ° C. That’s perfect for melting gold. It’s made from 99% pure aluminum oxide (Al2O3). This pureness is important. It implies almost no contamination gets involved in your molten gold. You obtain tidy outcomes each time.

The product is corundum. This is an extremely hard, thick form of alumina. It offers the crucible outstanding resistance to thermal shock. You can warm it up quickly. You can cool it down quickly. It will not break conveniently. This strength implies it lasts much longer than cheaper crucibles. You save money over time.

Its high thickness quits liquified metal from taking in. This makes cleansing simple. Just tap out leftover material. Chemical resistance is another big plus. Acids and bases do not harm it much. This purity and resistance safeguard your valuable gold. It maintains the thaw pure.

The crucible form is typical. It fits most conventional heaters and tongs. You won’t need special tools. Its surface is smooth inside. This quits material from sticking. You obtain almost all your gold back after putting.

Use it very carefully. Comply with the suggested cooling and heating prices. Don’t subject it to unexpected, severe temperature adjustments. Avoid mechanical impacts, particularly when warm. Manage it with appropriate ceramic tongs. This treatment makes certain maximum life. It’s a trusted, affordable device for major gold melting.

Applications of 1500-1800C high temperature 99 al2o3 alumina ceramic corundum crucible for melting gold

This crucible deals with severe heat needed for gold. It’s made from 99% pure alumina ceramic. Alumina is really difficult and stable. This pureness is important. It guarantees the crucible endures intense temperatures repetitively. Gold melts around 1064 ° C. Several procedures need much hotter settings. Smelting concentrates or refining often needs 1200 ° C to 1400 ° C. Some alloying or special procedures push temperature levels even higher. This crucible works reliably from 1500 ° C approximately 1800 ° C. That added warmth ability is crucial. It gives you a risk-free barrier.

The material resists chemical strike. Molten gold is very responsive. It won’t infect your melt. You get pure gold after pouring. Slag and flux products are aggressive too. The crucible endures them. Thermal shock resistance is another vital feature. You heat it quick. You cool it down quick occasionally. This crucible deals with quick temperature level adjustments well. It will not break conveniently. That conserves money. Damaged crucibles wreck batches.

Its structure is thick and non-porous. Nothing leaks with the walls. You lose no rare-earth element. Surface smoothness issues. Gold does not stick when putting. Cleaning is less complicated. Maintenance is simpler. This crucible lasts numerous cycles. You get value gradually. It fits standard melting heating systems. Jewellers utilize it. Refineries depend on it. Hobbyists discover it reputable. It executes regularly. Dealing with liquified gold needs safety. This crucible provides protection. Its high temperature score prevents hazardous failings. You work confidently.

5 FAQs of 1500-1800C high temperature 99 al2o3 alumina ceramic corundum crucible for melting gold

Here are 5 key FAQs about our 1500-1800°C high temperature 99% Al2O3 alumina ceramic corundum crucible for melting gold:

What’s the highest temperature this crucible can handle? This crucible is built for extreme heat. It reliably withstands temperatures up to 1800°C (3272°F). This is far hotter than gold’s melting point of 1064°C. You have a big safety margin. Never exceed 1800°C to prevent damage.

Why is 99% alumina purity important? Pure alumina fights contamination. Lower grades might add other materials. These impurities can leak into your molten gold. 99% Al2O3 keeps your gold pure. It ensures the melt stays clean. You get consistent, high-quality results.

Will gold stick to the crucible? Gold won’t stick or wet this surface. The alumina material is non-reactive. Your melted gold flows out easily. You lose less precious metal. Cleanup is simpler too. This saves you time and material.

Is this crucible resistant to thermal shock? Yes, it handles fast heating and cooling well. Alumina corundum has low thermal expansion. Sudden temperature changes cause less stress. The crucible heats up quickly. It cools down without cracking easily. This is vital for repeated melting cycles.

How long will this crucible last? Lifespan depends on your exact use. Factors include peak temperature, heating speed, and cooling method. Used correctly within its limits, it lasts for dozens of melts. Inspect it carefully before each use. Look for cracks or severe wear. Replace it if you see damage.
