Key Features and Technical Specifications
Gotrays alumina crucibles stand out thanks to their high-quality aluminum oxide (Al2O3) material. Made from at least 99% pure Al2O3, these crucibles deliver excellent heat resistance and durability, making them perfect for high-temperature tasks. Aluminum oxide is known for its strong chemical stability and ability to withstand extreme heat without cracking or deforming.
Here’s a quick breakdown of why this material works so well:
- High melting point: Over 3,700°F (2,040°C), ideal for metal melting and sintering.
- Chemical resistance: Stays unaffected by acids, bases, and most chemicals.
- Thermal shock resistance: Handles quick temperature changes without damage.
Size and Shape Guide
Gotrays offers alumina crucibles in various sizes and shapes to match different needs:
| Size (Diameter x Height) | Shape | Common Uses |
|---|---|---|
| Small (1-2 inches) | Cylindrical | Gold and silver assay, lab tests |
| Medium (2-4 inches) | High form dish | Metal casting, small batch melts |
| Large (4+ inches) | Open top bowl | Industrial sintering, ceramic work |
Choosing the right size and shape helps maximize capacity and efficiency. For example, a high form alumina dish is great for lab sample prep and thermal analysis, while a wider melting pot fits larger metal batches.
Gotrays alumina crucibles also come in custom shapes and sizes if you need something specific—perfect for applications requiring tailored dimensions or special lids.
Versatile Applications of Alumina Crucibles
Gotrays alumina crucibles are built to handle a wide range of high-temperature tasks. Whether you’re melting metals like gold, silver, or copper, these aluminum oxide crucibles hold up well in torches or furnaces, making metal casting smoother and more efficient.
In labs, they’re a go-to for TGA (Thermogravimetric Analysis), DSC (Differential Scanning Calorimetry), and sample prep. The high purity and thermal stability of our ceramic lab crucibles ensure accurate results and repeatable experiments every time.
On the industrial side, Gotrays alumina assay crucibles excel in processes like sintering and calcination. These are key steps in ceramics and glass making, where high-temperature alumina boats and refractory alumina vessels provide durability and resistance to thermal shock. Whether you work with custom Al2O3 calcination cups or need zirconia-enhanced alumina crucibles, our products cover the full spectrum of applied needs in manufacturing and research.

Expert Tips Handling Maintenance and Safety
To get the most out of your Gotrays alumina crucibles and keep them in top shape, follow these simple tips:
- Handle with care: Alumina crucibles are tough but can chip or crack if dropped. Use tongs or heat-resistant gloves when moving them, especially when hot.
- Avoid thermal shock: Let the crucible cool down slowly after heating. Sudden temperature changes can cause cracks. Don’t put a hot crucible on cold surfaces or into water.
- Clean properly: After use, clean your crucible with warm water and mild detergent. Avoid harsh chemicals or metal scrubbing pads that might damage the surface. For stubborn residues, soak before gently scrubbing.
- Store safely: Keep crucibles in a dry, stable place away from heavy tools or materials that could cause damage.
- Safety first: When using crucibles for metal melting or lab work, always wear appropriate PPE—heat-resistant gloves, safety glasses, and proper ventilation. Alumina is refractory but can release dust if broken, so handle broken pieces carefully.
- Inspect before use: Check your crucible for cracks or chips before heating. Damaged crucibles can fail under high heat, risking spills or accidents.
By following these tips, your Gotrays alumina crucibles will deliver consistent performance and last longer in demanding high-temperature environments.
