Rutile type MnF2 was shock-loaded to 3.6 - 33.4 GPa by impact of flyer plates accelerated by a propellant gun. Recovered samples were studied by X-ray powder diffraction and transmission electron microscope (TEM). The phase transition of rutile type to the α-PbO2 type structure was found in the recovered sample. The yield of α-PbO2 phase in the recovered sample increases up to about 10 GPa, and decreased at high pressures. The XRD line width of rutile phase (110) also has maximum at pressure of 10 GPa, and that of α-PbO2 phase (111) is broader than rutile phase and almost constant against shock pressure. The lamellae pattern, which consists of two crystal phases (rutile and α-PbO2 phase), was observed in the shock recovered sample from 8.3 GPa by TEM.
