Impact of copper substitution on the structural, ferroelectric and magnetic properties of tungsten bronze ceramics

Structural, dielectric and impedance spectroscopy analysis of Ba5CaTi1.94Zn0.06Nb8O30ferroelectric ceramic

“…Shilpi Jindal et al, 26 studied structural and dielectrical properties of lead-free polycrystalline electro ceramics Ba 5 -CaTi 2 Nb 8 O 30 (BCTN) for microwave tunable device applications. They found that the ceramic Ba 5 CaTi 2 Nb 8 O 30 (BCTN) was single-phase with a tungsten-bronze structure in space group P4bm.…”

Structural, Dielectric, and Magnetic Properties of Ba2Bi9-xFe5+xTi8O39 Tetragonal Tungsten Bronze Ceramics

“…In contrast to perovskites, these doping sites exercise the formation of a great variety of versatile compositions with profound physical properties and have the flexibility of multi-doping [8]. These sites can accommodate cations of various valences; the A-site interstices can accommodate divalent or trivalent cations while tetravalent or pentavalent cations are for the B-sites, while the C-sites are typically left empty for smaller cations [9]. Nonetheless, the C-site can also be filled; as some researchers have reported the Li + could be the participant of C-site [10].…”
