산업 응용 :
* 안료 생산 : It is a key precursor in the production of lithopone, a white pigment used in paints, inks, and plastics.
* Luminous Paints: Barium sulfide can be used to create phosphorescent materials, which emit light after exposure to ultraviolet light. This was particularly important in the past for making luminous paints used in dials, clocks, and other applications. However, its use has largely been replaced by safer alternatives.
* 화학 합성 : Barium sulfide is used in the synthesis of other barium compounds, including barium hydroxide and barium sulfate.
기타 응용 프로그램 :
* Depilatory Agent: In the past, barium sulfide was used as a depilatory agent (hair remover) in some hair removal products. However, its use has been discontinued due to its toxicity.
* Treating Leather: Barium sulfide was once used in tanning processes to remove hair and soften leather. This use has also been discontinued due to safety concerns.
중요한 고려 사항 :
* 독성 : Barium sulfide is highly toxic and should be handled with extreme care. It can cause severe skin, eye, and respiratory irritation, as well as systemic poisoning.
* 불안정성 : Barium sulfide reacts with moisture and air, decomposing and releasing toxic hydrogen sulfide gas. Therefore, it must be stored in airtight containers and handled with caution.
대안 :
Due to its safety concerns, barium sulfide's use has been largely replaced by safer alternatives in most applications. For instance, titanium dioxide has largely replaced lithopone as the primary white pigment.
결론 :
While barium sulfide has some industrial applications, its use is limited due to its toxicity and instability. Alternatives are widely available, and the handling and storage of this compound require strict safety precautions.
