99% High-Purity Alumina Funnel Crucible
Description:
Alumina funnel crucible is a specialized laboratory tool made from high-purity alumina (Al2O3) designed to combine the features of a crucible and a funnel.
It is primarily used in high-temperature laboratory processes where precise filtration, melting, or chemical reactions are required.
The funnel shape facilitates the pouring of liquids or molten materials, while the crucible design ensures that the container can withstand high temperatures.

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.
