U+785D "硝" CJK Unified Ideograph-# Unicode Character
U+785D "硝" CJK Unified Ideograph-# is a Chinese character (Hànzì) that primarily means saltpeter, niter, or potassium nitrate, a key ingredient in gunpowder and fireworks, and by extension refers to any substance that is salty or effervescent, such as in the word 硝烟 (xiāoyān) meaning gunpowder smoke or smoke of battle. In its chemical sense, 硝 is used to denote nitro compounds, like in 硝酸 (xiāosuān) for nitric acid and 硝化 (xiāohuà) for nitrification. The character is composed of the radical 石 (shí, meaning stone or rock) on the left, indicating its mineral or earthy nature, and the phonetic component 肖 (xiào), which contributes to its pronunciation. This logograph is commonly found in modern Mandarin contexts related to chemistry, mining, and military terminology, reflecting its historical importance in Chinese alchemy and warfare.
