'''碳酸鋅'''（{{lang-en|Zinc carbonate}}）是[[鋅]]元素的[[碳酸鹽]]，[[化學式]]'''ZnCO<sub>3</sub>'''<ref name=Kagaku50 />。碳酸鋅是菱鋅礦（{{lang|en|Smithsonite}}）中的主要成分，無臭、無味，性質不穩定，受熱分解出[[二氧化碳]]。

在[[工業]]領域，「碳酸鋅」一般指鹼式碳酸鋅（{{lang|en|Zinc carbonate hydroxide}}），化學式2ZnCO<sub>3</sub>・3Zn(OH)<sub>2</sub>・H<sub>2</sub>O<ref name=Kagaku50 />。

碳酸鋅是白色粉末狀[[固體]]，無臭、無味，不溶於[[水]]和[[醇類]]，微溶於[[液氨]]，能溶於稀酸和[[氫氧化鈉]]水溶液。碳酸鋅廣泛存在於菱鋅礦中<ref name=Webmineral/><ref>{{cite web | url=http://www.mnh.si.edu/onehundredyears/featured_objects/smithsonite.html | publisher=Smithsonian Institution | title=Smithsonite at the National Museum of Natural History | accessdate=8 December 2010 | archive-date=2016-01-21 | archive-url=https://web.archive.org/web/20160121212922/http://www.mnh.si.edu/onehundredyears/featured_objects/smithsonite.html | dead-url=no }}</ref>。

== 化學性質 ==
將碳酸鋅加熱到{{convert|300|C}}，分解為[[氧化鋅]]和[[二氧化碳]]<ref name=Kagaku50 />。這個過程稱為[[煅燒]]：
: <ce>{ZnCO3} \; \xrightarrow{\triangle} \; {ZnO} + {CO2\uparrow}</ce>

== 製備方法 ==
[[硫酸鋅]]和[[碳酸鈉]]反應生成碳酸鋅的[[沈澱]]和[[硫酸鈉]]：
: <ce>{ZnSO4} + {Na2CO3} \; \xrightarrow \; {ZnCO3\downarrow} + {Na2SO4}</ce>
