Ball Milling Of Pyrochlore Materials

2019-5-26The structural and compositional evolution of four members of the ANbWO6 A NH4 Rb H K defect pyrochlore family have been studied as a function of pressure up to 7 GPa using a diamond anvil cell and monochromatic synchrotron X-ray powder diffraction. In response to increasing hydrostatic pressure NH4NbWO6 and RbNbWO6 both initially contract but then undergo a fairly
