**硝酸鍶**是一種無機化合物，化學式為 Sr (NO3)2。

## 性質

硝酸鍶是一種無色或白色等軸晶系結晶，易溶於水、液氨，微溶於無水乙醇和丙酮。加熱時先放出氧生成亞硝酸鍶，繼續加熱則分解為氧化鍶，並放出一氧化氮和二氧化氮氣體：

　
: 2 Sr(NO3)2 — 高溫→ 2 SrO + 4 NO2↑ + O2↑

硝酸鍶為氧化劑，與有機物和還原劑接觸、摩擦、碰撞及遇火可能引起劇烈燃燒和爆炸。有毒！

## 製備

1、天青石用鹽酸溶解後除鈣，加入飽和碳酸鈉溶液沉澱出碳酸鍶，過濾，用硝酸溶解，再經壓濾、濾液蒸發濃縮、結晶、離心分離，得到硝酸鍶成品。

　
: ${\rm {\ SrSO_{4}+Na_{2}CO_{3}\rightarrow SrCO_{3}\downarrow +Na_{2}SO_{4}}}$

　
: ${\rm {\ SrCO_{3}+2HNO_{3}\rightarrow Sr(NO_{3})_{2}+H_{2}O+CO_{2}\uparrow }}$

2、由碳酸鍶與硝酸反應製備。反應方程式見上面。

## 用途

硝酸鍶用於製造紅色煙火，用於製造鐵路、航道和機場等的信號燈。國防工業中用於製造信號彈、火焰筒、曳光彈。也用於製造電視顯像管中的紅色發光劑、光學玻璃。還用於醫藥，製造螢光體。
