Barium sulfide is the inorganic compound with the formula Ba S. BaS is the barium compound produced on the largest scale. [ 3 ] It is an important precursor to other barium compounds including barium carbonate and the pigment lithopone , ZnS/BaSO 4 . [ 4 ]

Barium sulfite is the inorganic compound with the chemical formula BaSO 3. It is a white powder that finds few applications. It is a white powder that finds few applications. It is an intermediate in the carbothermal reduction of barium sulfate to barium sulfide : [ 2 ]
Barium carbonate is the inorganic compound with the formula BaCO 3. Like most alkaline earth metal carbonates, it is a white salt that is poorly soluble in water. It occurs as the mineral known as witherite. In a commercial sense, it is one of the most important barium compounds. [5]
The standard Gibbs free energy of formation (G f °) of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of a substance in its standard state from its constituent elements in their standard states (the most stable form of the element at 1 bar of pressure and the specified temperature, usually 298.15 K or 25 °C).
Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide: BaS + ZnSO 4 → ZnS·BaSO 4. This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO 4.
The reaction is performed in solution and the barium acetate crystalizes out at temperatures above 41 °C. Between 25 and 40 °C, the monohydrate version crystalizes. Alternatively, barium sulfide can be used: [2] BaS + 2 CH 3 COOH → (CH 3 COO) 2 Ba + H 2 S. Again, the solvent is evaporated off and the barium acetate crystallized.
