Process for producing barium sulfate, barium sulfate and use of barium sulfate |
| abstract |
In a process for the continuous production of microcrystalline lead sulfate particles, barium salt solution and sulfate solution are simultaneously brought together in a precipitation suspension with constant stirring, the precipitation suspension is continuously drawn off and the barium sulfate precipitate is filtered and washed. To produce platelet and / or needle-shaped barium sulfate particles, the barium salt solution has a concentration of 0.1 to 0.8 Ba 2+ mol / l and the sulfuric acid has a concentration of 0.1 to 2.0 SO 4 2 mol / l, the throughput and the stirring speeds being controlled while the precipitation volume is kept constant so that a pH value of 1 to 9 is present in the precipitation suspension. |
