硝酸鈣(Calcium Nitrate)是一種無機化合物,化學式為Ca(NO₃)₂,由鈣離子(Ca²⁺)和硝酸根離子(NO₃⁻)組成。根據英國皇家化學學會(RSC)的定義,它是白色結晶固體,易溶于水且吸濕性強,常以四水合物(Ca(NO₃)₂·4H₂O)形式存在。
在應用方面,硝酸鈣主要有以下用途:
生産上,硝酸鈣主要通過硝酸與碳酸鈣(或氫氧化鈣)中和反應制得,反應式為:
$$
text{CaCO₃ + 2HNO₃ → Ca(NO₃)₂ + CO₂↑ + H₂O}
$$
這一工藝被國際肥料工業協會(IFA)列為标準化生産方法。
安全性方面,其粉塵對呼吸道有刺激性,且高溫分解可能釋放有毒氮氧化物,需遵循職業安全與健康管理局(OSHA)的防護标準。
硝酸鈣(calcium nitrate)是一種無機化合物,化學式為 $text{Ca(NO}_3text{)}_2$,常見形态為四水合物 $text{Ca(NO}_3text{)}_2cdot4text{H}_2text{O}$。以下是其詳細解析:
如需進一步了解其工業制備方法或具體應用案例,可參考化學專業數據庫或權威文獻來源。
