Figure 3: Bond angle distributions for l-ZrO2 at 2,800 °C and c-ZrO2.
From: Atomic and electronic structures of an extremely fragile liquid

(a) The bond angle configurations Zr–Zr–Zr, (b) Zr–O–Zr, (c) Zr–Zr–O, (d) O–Zr–O, (e) O–O–Zr and (f) O–O–O. The B(θ)/sinθ data for c-ZrO2 has been scaled by a factor of 20 for clarity.
