The perovskite crystal structure
Ғылым және технология
The perovskite crystal structure, ABO3, is incredibly important. Many important technologies such as dielectrics, ferroelectrics, and more rely on materials in this crystal structure. The structure consists of two different cations (A and B) which must combine to be a +6 charge. Commonly a 2+ and a 4+ cation. The A cation sits at cube corners, the B cation sits at the unit cell center. The oxygen anion sits at face centers. Perovskites can be ideal or non-ideal. The lattice parameter based on connected B-O distances and A-O distances might not be the same leading to distortions (tilting) of octahedra.

Thanks for making such a fabulous video on perovskites.

Thanks so much!
Great video! Continue the work on making solid state chemistry explanations. Do you have an explanation for why the octahedra tilt into the cation to decrease the space around the cation? Are there certain effects that can explain this phenomenon?
Just few hours ago exam i am watching that video...No doubt it gives you something more than others one... I am grateful 💟

Thanks. Awesome Video. So if we wanted to calculate the density of perovskite we should use t(tolerance factor) instead of a(lattice parameter)?
Great video Sir. How can I find this structure in Vesta ? Is it available there?
Hi Taylors, very useful vedios. But I have a problem, how can we draw a atom distortion or atom tilt using the VESTA? I checked your serials vedios but I did not find any clue. I am thankful if you could offer some help. Thanks
Informative. Thanks. It would be great if you discuss about the wycaff possitions of coordinates... Like for my structure it shows for X3 mixed atom... So, can you provide me the postions coordinate for 3c positions for each X site atoms.

Good idea for future video.
What's the software, you used to represent Perovskite cubic ? Can I download it for free ? Thank you..❤️
Hello, first of all, I would like to thank you for the video. Which software did you use to show the structure of perovskite?

Vesta. I have a bunch of tutorials on how to use this software if you are interested. They are on my KZread channel
somedays, I feel like I'm not ideal other.... but then I pull myself together and straighten myself out! (get it?)

My polyhedral structure has two planes and i want to hide color of one plan so only atoms become obvious. I am adjusting plan color but it not giving results like in your distorted structure the central space is white without plan
