Embodiment 1
[0009] Aluminum fluoride with a water content of 6.58%, an F content of 59.89%, and an Al content of 29.85% is placed in the high temperature zone of a high-temperature static calciner at a temperature of 400°C for 30 minutes, and then cooled to obtain an aluminum fluoride product. The water content is 0.51%, the F content is 63.75%, and the Al content is 32.96%.
Embodiment 2
[0011] Aluminum fluoride with a water content of 5.48%, an F content of 60.10%, and an Al content of 30.25% is placed in the high temperature zone of a high-temperature static calciner at a temperature of 500°C for 25 minutes, and then cooled to obtain an aluminum fluoride product. The obtained water content is 0.49%, the F content is 63.92%, and the Al content is 33.10%.
Embodiment 3
[0013] Aluminum fluoride with a water content of 5.21%, an F content of 60.25%, and an Al content of 30.40% is placed in the high temperature zone of a high-temperature static calciner at a temperature of 600°C for 20 minutes, and then cooled to obtain an aluminum fluoride product. The water content is 0.43%, the F content is 63.98%, and the Al content is 33.25%.
