Title: 6H hexagonal structure of low loss Ba{sub 3}MTiWO{sub 9} (M = Mg, Zn) dielectrics

Abstract

The crystal structure of Ba{sub 3}MTiWO{sub 9} (M = Mg, Zn) oxides has been found to be 6H hexagonal, space group P6{sub 3}/mmc, parameters of unit cell: a = 5.7943(1) A, c = 14.1642(1) A and a = 5.7993(1) A, c = 14.1626(1) A for M = Mg and Zn, respectively. The tungsten and titanium atoms are randomly distributed in pairs of face-sharing octahedra separated by octahedral layers containing magnesium or zinc. It was revealed that the structures are well ordered which is believed to result in a low dielectric loss at a microwave frequency reported for these materials.
