Product Details
ZYLAB rectangular crucible for tube furnace is made from alumina with a purity of over 99%, specifically designed for tube furnaces and other high-temperature applications. It offers excellent high-temperature resistance and thermal stability.
The rectangular design ensures uniform heat distribution during the heating process, while the hole at the back allows for easy insertion and removal of materials during experiments.
This crucible is widely used in high-temperature experiments such as metal processing, ceramic sintering, and glass melting, making it particularly suitable for laboratory environments that require high temperature, high purity, and precise control.
Alumina Purity: >99%
Maximum temperature resistance: 1750°C
Continuous operating temperature: ≤1600°C
We offer customized services according to your requirements!
How to Use Alumina Crucibles？
1. Before the first use, preheat the crucible in an oven at around 105°C for 120 minutes to remove moisture.
2. Do not directly heat the crucible with gasoline blowtorch, acetylene torch, or alcohol burner to avoid uneven heating and cracking of the product.
3. The heating or cooling rate should not be too fast. The temperature change below 1200°C should be <5°C/minute, and above 1200°C should be ≤4°C/minute.
4. The distance between the product and the heating element (such as carbon tube, silicon molybdenum rod, or heating wire, etc.) should be >2cm.
5. The bottom of large crucibles should preferably not directly contact the bottom of the furnace. It is recommended to use alumina foot pads or other heat-resistant materials to lift the crucible, forming air convection to prolong the service life of the product.
