Claim Text:
1. A method for preparing barium titanate product, comprising: 1) preparing a Ba—Ti mixed solution by: dissolving BaCl 2) preparing a synthetic agent by: adding ammonia and ammonium bicarbonate into deionized water and preparing the synthetic agent in solution, the synthetic agent having a NH 3) preparing barium titanate by: adding the Ba—Ti mixed solution, the mixed solution having a flow rate of 100-4000 L/h, and the synthetic agent, the synthetic agent having a flow rate of 100-4000 L/h, into a reactor for synthesis reaction thereby obtaining a slurry; 4) separation: separating the slurry from step 3) by pressure filtration, thermal washing the obtained solid, then pressure filtering and obtaining a filter cake; 5) calcination: calcining the filter cake from step 4) for 1 hour at 590-610° C., and then calcining for an additional 2 hours at 700-950° C.; and 6) crushing: crushing the solid from step 5) by using a crusher to obtain the barium titanate product.
