Barium sulfide - Wikipedia
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 BaCO 3 and the pigment lithopone, ZnS/BaSO 4. [4] Like other chalcogenides of the alkaline earth metals, BaS is a short wavelength emitter for electronic ...

2021年10月14日 · Barium sulfide (BaS) is a sulfide of barium found naturally as the mineral barite. It is colorless, although like many sulfides, it is commonly obtained in impure colored forms.It is considered to be the most important synthetic material of barium , being the precursor to barium carbonate and the pigment lithopone .

Barium sulfide is prepared commercially by heating barite (BaO) with coal or petroleum coke in a rotary kiln at 1000 °C to 1250 °C in an oxygen-free atmosphere. The product, black ash, is a gray or black powder containing carbonaceous impurities and unreacted barite.

… sulfate with charcoal to synthesize barium sulfide. Exposure to sunlight caused the phosphor to emit a long-lived yellow glow, and it was sufficiently regarded that many traveled to Bologna to collect the mineral (called Bologna stones) and make their own phosphor.
