To be more detailed, so that experts can provide answers and we can also study earnestly*. :handshake
The solubility of barium carbonate is lower, right? It’s just a wild guess.
It’s not a big problem; some devices in China use barium carbonate!
Is it really possible? What is the difference in solubility between barium carbonate and barium sulfate? Could the person upstairs explain it in more detail? We all study *study*.
The customer did not specify which reaction exactly, and wanted to use barium carbonate as a substitute for barium chloride. The solubility of barium carbonate is much lower than that of barium chloride. And barium sulfate has a much higher solubility than barium carbonate

It can handle SO4 and Ca ions simultaneously; there are specific requirements for barium carbonate (mainly regarding particle size), and there are also requirements regarding the reaction conditions (temperature).
In China, barium carbonate is used as a substitute for barium chloride, and there are relevant literature sources available for reference. It should be noted, however, that the solubility of barium carbonate in water is 1.72 milligrams per 100 milliliters of water, making it quite difficult to prepare an appropriate suspension for inclusion. It is said that it can remove a small amount of calcium and magnesium ions at the same time. I’ve tried it, but the effect isn’t very noticeable.
After the use of barium carbonate, it has a certain impact on subsequent calcium treatment, and precipitates will form within the system. Use under acidic conditions. There is corresponding literature available on it.

From a control perspective, barium carbonate is less effective than barium chloride, as barium chloride is added in solution form, and any excess barium can be removed later in the purification process by adding carbonates. After further acidification, it can be fed into the tank. Also, the claim on the 6th floor that the solubility of barium sulfate is greater than that of barium carbonate is nonsense; if that’s the case, how can sulfate ions be removed?
If barium carbonate can indeed replace barium chloride, it would have a significant impact on reducing production costs. However, it might be difficult to control in the manufacturing process. I’ve seen that barium carbonate has low solubility in water, but its solubility is slightly higher in brackish water. If it’s possible to use brackish water obtained through electrolytic dechlorination as a solvent for barium carbonate, then several problems could be solved.
