About
The character "硝" is structurally composed of the semantic radical "石", denoting stone or mineral, and the phonetic component "肖", which historically guided its pronunciation, together forming a phono-semantic compound that originally designated saltpeter, a nitrate mineral found in nature as a crust on rocks or in soils. Its etymology clearly links the substance to its mineral origin, and while the character's form has remained consistent, its semantic application has broadened from solely referring to saltpeter to encompassing a range of nitrate-based compounds and processes, such as in the terms for nitric acid or the nitrating agents used in traditional alchemy, early medicine, and later industrial chemistry, without departing from its core association with nitrates.
