Why are sphalerite and wurtzite structures polymorphic

Sphalerite and wurtzite are both zinc iron sulfides with the same formula, Zn, FeS. The sphalerite and wurtzite are said to be polymorphic explain. The complete morphology of a material is described by polymorphism and other variables such as crystal habit, amorphous fraction or crystallographic defects.

Wurtzite is the not so common cousin of the much more common mineral, sphalerite.

Why are sphalerite and wurtzite structures polymorphic
However what makes them different minerals is that they have different structures. You can follow the question or vote as helpful, but you. The two are called polymorphs meaning many shapes and actually share the chemistry with a third, even rarer, mineral called matraite. There are quite contradictory data about the polymorphism of zinc chalcogenides in the literature. In materials science, polymorphism is the ability of a solid material to exist in more than one form or crystal structure. Its color is usually yellow, brown, or gray to gray-black, and it may be shiny or dull.

The optical properties of the semiconductor ZnS in wurtzite structures are considerably enhanced, but the lack of structural stability limits technological applications.

Sphalerite is a mineral that consists largely of zinc sulfide in crystalline form, but it almost always contains variable amounts of iron. God offers his friendship freely to all, but many.
