Barium carbonate is made commercially from barium sulfide by treatment with sodium carbonate at 60 to 70 °C (soda ash method) or, more commonly carbon dioxide at 40 to 90 °C: In the soda ash process, an aqueous solution of barium sulfide is treated with sodium carbonate: [5] BaS + H 2 O + CO 2 → BaCO 3 + H 2 S

Witherite is a barium carbonate mineral, Ba C O 3, in the aragonite group. [2] Witherite crystallizes in the orthorhombic system and virtually always is twinned. [2] The mineral is colorless, milky-white, grey, pale-yellow, green, to pale-brown.

Barium oxide from metalic barium readly forms from its exothermic oxidation with dioxygen in air: 2 Ba(s) + O 2 (g) → 2 BaO(s). It's most commonly made by heating barium carbonate at temperatures of 1000–1450 °C. BaCO 3 (s) → BaO(s) + CO 2 (g) Likewise, it is often formed through the thermal decomposition of other barium salts, [6] like ...
Barium hydroxide is occasionally used in organic synthesis as a strong base, for example for the hydrolysis of esters [8] and nitriles, [9] [10] [11] and as a base in aldol condensations. There are several uses for barium hydroxide such as to hydrolyse one of the two equivalent ester groups in dimethyl hendecanedioate.

Barium selenide can be obtained by the reduction of barium selenate in hydrogen flow:. [3] [5] BaSeO 4 + H 2 → BaSe + 4 H 2 O. It can also be obtained by reacting selenium with barium carbonate or barium oxide at high temperature: [citation needed] 2 BaCO 3 + 5 Se → 2 BaSe + 3 SeO 2 + CO 2
