✦ Synopsis

ples were characterized by X-ray powder diffraction, XRD A previously unreported solid solution based on fresnoite, (Philips PW1710), and the observed peaks were compared Ba 2 TiSi 2 O 8 , has been found in the BaO : TiO 2 : SiO 2 system. It with JCPDS card 22-513. Data for Rietveld refinement forms by partial replacement of Si by Ti and has the formula were collected on a Stoe Stadi/P automated diffractometer Ba 2 Ti 1؉x Si 2؊x O 8 (0 Յ Յ x Յ Յ 0.14). Infrared spectra confirm that in transmission mode using CuKͰ 1 radiation (Ge monothe excess Ti is tetrahedrally coordinated.
