Growth of single crystals of the high-pressure phase of α-PbO2

The technique and results of hydrothermal growth of single crystals of the high-pressure phase of α-PbO2 are described. Dark brown crystals of predominantly prismatic habit with characteristic sizes of 550 × 100 × 150 μm3 were obtained at p = 4 GPa by cooling an aqueous solution in the temperature range t = 600–300°C.
