Zinc blende or $ZnS$ also known as sphalerite has a cubic close packing structure also known as face – centred cubic structure. ... In zinc blende structure, zinc ions occupy half of the tetrahedral sites. Each of the ions is 4 – coordinate and has local geometry.

How many atoms are in zinc blende structure?

Of course we see immediately that what many call Zinc blende or sphalerite is simply an fcc lattice with two atoms in the base: atom A at (0,0,0,) and atom B at (½, ½, ½).

What is zinc blende main composition?

Summary: Zinc blend is a compound that comes in two forms: sphalerite and wurtzite. These are characterized by a 1:1 stoichiometric ratio of Zinc to Sulfur. It maintains a tetrahedral arrangement in both forms.
