4: Selection of salts and calcination conditions: Under normal circumstances, the original ingredients are added in the form of tears, and sintered in the form of oxides after heating. Salts have a layered structure, and this structure is often not completely destroyed when it is decomposed. If the structural correlation between the raw salts and the products is maintained, the type of salts, decomposition temperature and time will affect the sintered Oxides.
