How to Use Alumina Saggar?
1. Before the first use, preheat the saggar in an oven at around 105°C for 120 minutes to remove moisture.
2. Do not directly heat the saggar 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 saggars 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 saggar, forming air convection to prolong the service life of the product.
