for calcination. The ATH is calcined to form alumina, which can be directly used for aluminum processing or can be used for ceramic applications:
2Al(OH)3 → Al2O3 + 3H2O
If the ATH is to be used for ceramics, it can undergo multiple washing steps to reduce the ionic sodium to less than 0.01 percent. The particle size of the calcined powder is reduced in size, depending on specifications determined by the end user.
