'''염화 바륨'''({{llang|en|Barium chloride}} 화학식: [[바륨|Ba]][[염소 (원소)|Cl<sub>2</sub>]])은 [[염소 (원소)]]와 [[바륨]]의 화합물로, 물에 녹는 [[바륨]]염이다. 독성이 있으며, 무색의 결정이다. 레이크 안료, [[매염제]], [[살충제]], 분석용 시약 등으로 쓰인다. (이수화물임)

== 준비 ==
:<chem>Ba(OH)2 + HCl -> 2H2O + BaCl2 </chem>
:
:<chem>BaSO4 + 4C -> BaS + 4CO</chem>
첫 단계에는 높은 온도가 요구된다.
:<chem>BaS + CaCl2 -> BaCl2 + CaS</chem>
