Product Details
99% High Purity Alumina Crucibles for Metallurgy Use is a laboratory or industrial container made from high-temperature-resistant alumina material with a purity of over 99%. It features a square shape and comes with a matching lid.
This type of crucible is commonly used in muffle furnaces, tube furnaces or crucible furnaces for processes that involve controlled heating, melting, sintering, or chemical reactions at high temperatures.
It is widely applied in fields such as materials science, metallurgy, ceramics, and chemistry.
Alumina Purity: >99%
Maximum temperature resistance: 1750°C
Continuous operating temperature: ≤1600°C
The lid can be purchased separately.
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.
