Decomposition of MgF_2 in the Tr5ansmission Electron microscope

摘要

The decomposition of thin MgF_2 crystals,crystallized by chemical vapor transport,can be observedin brightfield mode in the transmission electron microscope,EELS and diffraction studies showe dthat the decomposition process leads via metallic magnesium to MgO.Single crystals from MgF_2 were obtained bychemical vpor transport using iodine as transport agent.
