Ceramic Pigments with Perovskite Structure

Advances in Science and Technology, 2006
The results of preliminary investigation on preparation of perovskite pigments by solid state reaction are presented. The effects of different raw materials used as component carriers on formation of colored pigments were examined. Pigment composition, optimum chromophore addition, type of mineralizer and the conditions of synthesis were determined ...

Structural phase transitions in perovskite layer structures

Ferroelectrics, 1980
Abstract Perovskite type layer-structure compounds of the formulas (Cn H2n+1 NH3)2·MCl4 and NH3 (CH2)n NH3MCl4 (M = Cd, Mn, Cu, Fe, n = 1–18) exhibit a variety of structural phase transitions which are connected with the dynamics of the alkyl-ammonium or alkylenediammonium chains respectively.

Perovskite: The Electrically Active Structure

Ferroelectrics, 2009
Metal oxides that have particularly strong electrical responses very frequently have the perovskite structure, or incorporate elements of that structure into more complex arrangements. These include ferroelectrics, piezoelectrics, and superconducting oxides. These structures often involve alternating layers in coherent, intergrowth patterns. It will be

New seignettomagnets with perovskite structure

Ferroelectrics, 1978
Abstract Complex investigations of compounds with the perovskite type A2BReO6 (A=Ba, Sr; B=Li, Mg, Zn, Ca, Mn, Fe, Co, Ni) and PB2BReO6 (B=Mg, Fe, Co, Ni) were performed.

Defect structure in perovskite titanates

Current Opinion in Solid State and Materials Science, 1996
Abstract Recent results have been obtained on the defect chemistry of perovskite ferroelectrics and have been applied to polarization fatigue in thin film ferroelectric memories, in other words the loss of switchable polarization after repeated switching cycles.

Structural origin of relaxor perovskites

Journal of Physics and Chemistry of Solids, 1996
Abstract Relaxor behavior of a diffuse phase transition and large frequency dispersion requires a small and broadly distributed activation barrier for interstate transitions. This can best be realized in a relatively random environment that apparently is provided by many complex perovskites, including those containing Pb. On the other hand, while the

Structural secrets of hybrid perovskites

Science, 2020
Hybrid Perovskites The optoelectronic and photovoltaic applications of polycrystalline hybrid metal halide perovskite films are notable because grain boundaries in most materials cause scattering of charge carriers that decreases performance. Electron microscopy studies of these materials have been hindered by their rapid structural degradation under ...

Perovskite and Related Structure Systems

1998
Perovskite and perovskite-related structures are important crystallographic structures particularly for oxide functional materials because most of the newly discovered functional materials belong to this category (for a complete list of perovskite structures, see Galasso, 1969, 1990).

Structural softness in photovoltaic perovskites

Applied Physics Letters
Perovskite photovoltaics (PVs) are a compelling candidate as a next-generation energy harvesting technology owing to the outstanding optoelectronic properties, low cost, and facile fabrication of perovskite materials. In the meantime, unsolved issues in perovskite stability still challenge the prospect of final commercialization. Recently, many studies
