'''碳化钡'''是[[钡]]的一种[[碳化物]]，化学式{{chem|BaC|2}}。钡另有一种碳化物BaC<sub>6</sub>。{{cn}}

== 制备 ==
碳化钡可以由钡和[[碳]]在1300 °C下直接反应而成。<ref>seilnacht.com: [https://www.seilnacht.com/Lexikon/56Barium.htm Seilnachts Periodensystem: Barium] {{Wayback|url=https://www.seilnacht.com/Lexikon/56Barium.htm |date=20210526151224 }}, abgerufen am 13. Dezember 2014</ref>

它也可以由[[硫酸钡]]、[[红磷]]和碳反应而成。<ref name="R. K. Sharma">{{cite book| author=R. K. Sharma | title=Chemistry Of Hydrides And Carbides | publisher=Discovery Publishing House | ISBN=978-8183562270 | date=2007 | page=295 }}</ref>
