Zinc Blende crystal structure
Ғылым және технология
The zinc blende crystal structure is the structure named for the low-temperature phase of the ceramic ZnS. It is cubic with two interpenetrating FCC lattices. One at the normal position and one at (1/4,1/4,1/4). Another way to think of it is an FCC lattice with half of its tetrahedral interstitials filled. The structure has 8 atoms per unit cell (4 formula units of ZnS). The lattice parameter can be found by noticing that atoms touch along body diagonal. 1/4*sqrt(d)*a=R_cation+R_anion. The compound has another phase, wurtzite, that is hexagonal and stable at high-temperature.

lol. woohoo!! So glad it helped!
THIS IS THE ABSOLUTE BEST
watching from India . thanks a lot for this cleared my doubt ,,,
thank you soooooooo much
Woohoo so this is called awsm crystal clear explanation... Teacher by birth?

Lol. It's in my genes!
hey, thanks for the vid. zinc blende has rc/ra = 0.326 and it has tetrahedral geometry, as you said in the video. But afterwards, you were talking about how it's a cubic crystal structure. But cubic ones are stated as 0.732-1?? is it both at the same time or sth?
What is the structure of the zn unit cell?
Sir Please upload a video regarding ZnS wurtzite structure.
