ígwè sulfide abụọ

Ígwè sulfide abụọ: Ntuziaka zuru okeIron abụọ sulfide, nke a makwaara dị ka ferrous sulfide, bụ ngwakọta kemịkalụ nwere usoro FeS. Ntuziaka a na-enye ntụle zuru oke nke njirimara ya, njikọ ya, ngwa na ihe nchekwa ya.

Njirimara nke Iron Sulfide Abụọ

Iron sulfide abụọ dị n'ụdị kristal dị iche iche, nke a na-ahụkarị bụ pyrrhotite ịnweta sitere n'okike.
