Abstract:

The crystal structure of Ba_2CdMoO_6 have been investigated by means of X-ray powder method, precise measurement of lattice parameters and other methods,using specimens prepared by solid state sintering method. We confirmed Ba_2CdMoO_6 belonging to cubic system at room temperature, with space group Fm3m. And we obtained that the lattice parameter is a=0.83354 nmat room temperature. Simultaneously we defined that Sr_2CdMoO_6 is new compound, it belongs to orthorhombic system and the lattice parameters: a=0.81931 nm, b=0.57694 nmand c=0.58406 nmat room temperature, The space group may be P_(mm2).
