What 锍 means
Read it as matte, not a finished metal. In nonferrous metallurgy, 锍 names the sulfide melt made when copper, nickel, lead, or similar sulfide ores are smelted. It gathers valuable metal sulfides for later treatment, before sulfur is removed and the metal is recovered.
The history is specialized rather than ancient. The Taiwan Ministry of Education's 2024 entry for 鋶 says it is not recorded in 說文 and lists no available record in several major historical dictionaries. The documented pair is traditional 鋶 and simplified 锍. The same spelling also names sulfonium in chemistry, so context decides the field. As of 2026, no source checked here establishes a separate premodern or regional reading.
Specialist Chinese: metallurgy first, chemistry second; it is not ordinary chat vocabulary.
If you meant sulfur, use 硫; 锍 is the matte or sulfonium term.
