【Abstract】 Used manganese sulfate and ammonium as material, a new process to prepare high volume density manganese carbonate was introduced. Some improved measures, such as order adding crystal seeds, select the propulsive agitator, install the buffle, and increase the reaction temperature, were taken to increase the volume density of product. The volume density of product could be up to 2.3 g/cm~3.更多还原
