**過錸酸鋇**是一種無機化合物，化學式為 Ba (ReO4)2。

## 製備

過錸酸鋇可由過錸酸和氫氧化鋇在水中反應得到：

　
: : ${\mathsf {2HReO_{4}+Ba(OH)_{2}\ {\xrightarrow {}}\ Ba(ReO_{4})_{2}+2H_{2}O}}$

## 物理性質

過錸酸鋇是白色固體，可溶於水，其溶解度隨著溫度的升高而升高。微溶於乙醇和甲醇。

它從溶液中可以析出二水合物

和四水合物
，它們在真空中加熱至 120℃失水。
.

Ba(ReO4)2·4H2O 晶體屬單斜晶系，空間群為_**P 21/n**_，晶胞參數為 _a_ = 0,7376nm, _b_ = 1,2452nm, _c_ = 1,2173nm, β = 90,04°, Z = 4。
