Abstract
High-pressure Raman study on Pb5Ge3O11 reveals the occurrence of an ir reversible phase transition from crystalline to amorphous state above 14.6 GPa. The (GeO4)4- tetrahedra is still retained but highly distort ed in the pressure-induced amorphous Pb5Ge3O11. The crystallization pr ocesses of the pressure-induced amorphous Pb5Ge3O11, investigated by m eans of Raman scattering, are similar to those of the melt-quenched am orphous form.
