'''硫化钡'''（[[化学式]]：[[钡|Ba]][[硫|S]]）是[[钡]]的[[硫化物]]，室温下为白色[[等轴晶系]]晶体，不纯时为浅灰色、黄绿色、浅棕色或黑色的粉末。它是第一个制得的[[磷光体]]材料，性质和制备都因此而被广泛研究过。<ref>Vij, D. R.; Singh, N. "Optical and electrical properties of II-VI wide gap semiconducting barium sulfide"  Proceedings of SPIE-The International Society for Optical Engineering  (1992),  1523(Conf. Phys. Technol. Semicond. Devices Integr. Circuits, 1992),  608-12.</ref>

用适量的[[硫]]处理硫氢化钡的水溶液或[[醇]]溶液，便可得到橙黄色的[[多硫化钡]]。

它在潮湿空气中水解放出有毒的[[硫化氢]]气体，与水或酸反应也会生成硫化氢，其他产物是[[氢氧化钡]]、硫氢化钡或其他钡盐。可以从饱和溶液析出六水合物（BaS·6H<sub>2</sub>O），六方片状晶体。硫化钡有毒，食入会造成中毒，水溶液具碱性，对皮肤和毛发有腐蚀性和脱毛作用。

==制取==
工业上，硫化钡是从[[重晶石]]矿制取其他钡化合物的中间体，可用于制取[[碳酸钡]]、[[氯化钡]]和[[立德粉]]等其他材料。<ref>Holleman, A. F.; Wiberg, E. "Inorganic Chemistry" Academic Press: San Diego, 2001. ISBN 0-12-352651-5.</ref>重晶石的主要成分为[[硫酸钡]]，用[[煤]]粉还原就可得到硫化钡：<ref>F.
