A review on tungsten bronze ferroelectric ceramics as electrically tunable devices

Structural and impedance spectroscopic study of Zn-substituted Ba5CaTi2Nb8O30 tetragonal tungsten bronze ceramics

“…Recently, tungsten-bronze compounds have been considered as one of the candidates to replace lead-based compounds [11,12]. As for perovskites, tungsten-bronze compounds (TTBs) have also attracted attention recently for their remarkable dielectric and ferroelectric properties and their various applications in the electronic, chemical and energy conversion sectors [13][14][15][16]. TTBs consist of distorted BO6 octahedra linked by their summits, leading to three different kinds of sites between them: A1, A2, and C. Thus, their general formula is [(A1)2(A2)4(C)4][(B1)2(B2)8]O30.…”

Relationship between structural and dielectric properties of Zn-substituted Ba5CaTi2−xZnxNb8O30 tetragonal tungsten bronze

“…Lead-free materials have an important place in electronics due to technological progress, the toxicity of lead and the desire to protect the environment 1-3 . Tetragonal tungsten bronzes (TTBs) are materials derived from the perovskite structure which, due to their polyvalent structure, can have very important and advantageous electrical, magnetic, catalytic, optical or photocatalytic properties, with diverse applications in the electronics, chemical and energy conversion sectors [4][5][6][7][8] . Recently, tungsten bronze compounds had been considered as one of the candidates to replacing lead compounds 9,10 .…”

Structural, electrical and relaxor properties of Sc-In solid solution in tetragonal tungsten bronze ceramics

“…Tetragonal tungsten bronzes (TTBs) are ceramic materials derived from the common perovskite unit, which due to their versatile structure may exhibit very interesting and useful electrical, optical, magnetic, catalytic or photocatalytic properties, with various applications in the optoelectronic, energy conversion or chemical sectors [1][2][3][4][5]. Recently, they received much of attention in the research community mainly due to their versatile structure [1,[6][7][8]:…”
