kësterite
Sign in to saveAlso known as kesterite, isostannite
Kësterite is a sulfide mineral with a chemical formula of . In its lattice structure, zinc and iron atoms share the same lattice sites. Kesterite is the zinc-rich variety whereas the zinc-poor form is called ferrokesterite or stannite. Owing to their similarity, kesterite is sometimes called isostannite. The synthetic form of kesterite is abbreviated as CZTS (from copper-zinc-tin sulfide). The name kesterite is sometimes extended to include this synthetic material and also CZTSe, which contains selenium instead of sulfur. Along with perovskite, recent advances have made kesterite promising mat

==Occurrence== Kesterite was first described in 1958 in regard to an occurrence in the Kester deposit and the associated locality in Ynnakh Mountain, Yana basin, Yakutia, Russia, where it was discovered.
