- •
First report on high pressure-high temperature (HP-HT) structural study of Dy6UO12.
- •
HP studies show structural stability up to 21 GPa in rhombohedral structure.
- •
Pressure induced structural disorder seen above 21 GPa.
- •
HP-HT studies show that Dy6UO12 remains stable up to 11.3 GPa and ∼673 K.
- •
The thermal expansion coefficients increase with pressure.
