Common Uses of Barium | Owlcation

Equally fascinating is how barium sulfate is the most abundant natural ore for barium and hense the starting point. It should be pointed out that intense heating of barium sulfate with carbon at 1100 Celsius will produce barium sulfide. Barium sulfide in water will even react with carbon dioxide forming barium carbonate and hydrogen sulfide.

Barium sulfate Revolvy

In contrast to barium sulfate, barium sulfide is soluble in water and readily converted to the oxide, carbonate, and halides. To produce highly pure barium sulfate, the sulfide or chloride is treated with sulfuric acid or sulfate salts: Barium sulfate produced in this way is often called blanc fixe, which is French for "permanent white."
