**磷化鋇**是一種無機化合物，化學式為 Ba3P2，可由多磷化鋇和金屬鋇反應製得，其具有反 Ce2S3 型的立方結構。鋇和紅磷按化學計量比在 800 °C 的氬氣氣氛中反應，也能得到 Ba3P2。

## 性質

磷化鋇可以迅速水解，並放出磷化氫：

　
: ${\mathsf {Ba_{3}P_{2}+6H_{2}O\ {\xrightarrow {}}\ 3Ba(OH)_{2}+2PH_{3}\uparrow }}$

它和非氧化性酸也能發生類似反應：

　
: ${\mathsf {Ba_{3}P_{2}+6HCl\ {\xrightarrow {}}\ 3BaCl_{2}+2PH_{3}\uparrow }}$
