Lead magnesium niobate (PMN) is a relaxor ferroelectric material. Because of its high dielectric constant and superior electrostrictive properties it is commonly used in the manufacture of multilayer electronic devices which is typically produced by tape casting. However, preparation of PMN slurry formulations to use in aqueous tape casting process is not investigated in detail yet. Therefore, in this study aqueous PMN formulations were developed for tape casting and its relation with the final properties of PMN films were investigated. The slurries were prepared using poly(acrylic acid)-based comb polymer as the dispersant, nonionic acrylic latex as the binder and the hydroxypropyl methyl cellulose as the wetting agent. The results showed that it is possible to prepare flexible, crack-free PMN films using highly concentrated suspensions without using any plasticizer. The study gives guidelines for the aqueous tape casting of PMN and can be adapted to processing of other multi-component metal oxides.

“…The diluted resin allows the incorporation of higher filler concentrations without significantly increasing the viscosity. Ceramic-polymer composites can typically be fabricated using low temperature processing techniques [3][4][5][6][7][8] . The traditional approach for preparation of such composites, especially composite films, is to mix a dielectric polymer solution and submicron-or micron-sized ferroelectric particulates, and evaporate the solvent of the polymer solution [3][4][5][6][7][8] .…”

The most common process for enhancing the dielectric permittivity of a polymer is to disperse a high dielectric permittivity insulating ceramic powder such as Barium Titanate (BaTiO 3 ) 9-11 or lead titanate (PbTiO 3 ) 12 into the polymer to form a composite.…”

Rapid growth of electronic industry requires development of new materials that combine the high dielectric constant intrinsic to ferroelectric ceramic materials with easy processing characteristics of polymers. Ceramic-polymeric composites possess interesting properties for a variety of electronic applications including passive electronic devices. In fact, polymer-ceramic materials have drawn lot attention for use in microelectronic packaging, because they can give higher performance with lower cost, size and weight. In this work, attempts are made to prepare ceramic polymer composites followed by characterization of dielectric properties. The Barium Titanate ceramic powders are synthesized using the hydrothermal process. Crystal structure and crystallite size of particles are determined using X-ray diffraction. Silane treatment is carried out on Barium Titanate powder to increase its compatibility with polymer, followed with preparation of ceramic polymer composites. Epoxy and polyvinyledene fluoride (PVDF) polymers are used as matrices for preparation of the composites. The proportion of nanopowder is varied from 60 to 90 wt%. Dielectric properties such as volume resistivity, dielectric constant, dissipation factor are evaluated. Results indicate that the dielectric constant and dissipation factor vary between 18 -140 and 0.01 to 0.09, respectively as the relative ratio of polymer and silane modified Barium Titanate is varied. Specifically, at 90 wt% of 0.1 wt% silane modified Barium Titanate, the highest dielectric constant of 140 along with dissipation factor of 0.07 is obtained in the epoxy based system.

RESUMENCon el objetivo de estudiar nuevos materiales multipropósito, en este trabajo se analizó la influencia de las partículas de Fe 3 O 4 y BaTiO 3 sobre las propiedades magnéticas y dieléctricas de los sistemas Fe 3 O4/BaTiO 3 /epoxi. A tal efecto se analizaron los sistemas bifásicos Fe 3 O 4 /epoxi y BaTiO 3 /epoxi y a partir del análisis de los resultados se conformaron los compuestos Fe 3 O 4 /BaTiO 3 /epoxi. En todos los casos los valores de permitividad y pérdidas dieléctricas fueron altamente influenciados por el contenido de carga. En este sentido, los materiales procesados con Fe 3 O 4 presentaron muy elevadas pérdidas dieléctricas para altas concentraciones de carga debido a efectos de percolación y a las propiedades semiconductoras del Fe 3 O 4 .Palabras claves: Materiales compuestos, propiedades dieléctricas y magnéticas. Microstructure and properties of Fe 3 O 4 /BaTiO 3 /epoxy composites ABSTRACTThe influence of Fe 3 O 4 and BaTiO 3 on dielectric and magnetic properties of Fe3O4/BaTiO3/epoxy composites was studied. Initially, biphasic Fe 3 O 4 /epoxy and BaTiO 3 /epoxy composites were analyzed, and based on these results Fe 3 O 4 /BaTiO 3 /epoxy composite were conformed. In all the cases, dielectric properties were influenced by the frequency and filler concentration. In this way, Fe 3 O 4 /epoxy composites with high filler concentration showed high dielectric loss due to percolation effects and semiconducting properties of Fe 3 O 4 .Keywords: Composite materials, dielectric and magnetic properties. INTRODUCCIÓNLos materiales compuestos epoxi-BaTiO 3 , son desde hace varios años, una alternativa viable en la fabricación de condensadores integrados (CI) [1][2][3][4][5], dado que combinan la procesabilidad y baja temperatura de curado de la resina con la alta permitividad del cerámico [6][7].La necesidad de reducir aún más los costos de producción y el tamaño de los circuitos electrónicos, ha impulsado el estudio y desarrollo de nuevos materiales compuestos con aplicaciones múltiples. Estos sistemas, que poseen dos o más propiedades funcionales, pueden ser empleados en la fabricación, tanto de inductores como de condensadores o resistores, con bajos costos y tiempos de producción. A tal efecto, los compuestos Fe 3 O 4 /BaTiO 3 /epoxi, pueden cubrir algunos de estos requerimientos. Al igual que los compuestos epoxi/BaTiO 3 , estos materiales cuentan con la facilidad de procesamiento de las resinas epoxi, buena permitividad del titanato, y también con propiedades ferrimagnéticas debido a la presencia de la Fe 3 O 4 [8][9].Uno de los principales problemas que presentan estos sistemas es la dificultad de combinar eficientemente las propiedades de cada fase sin afectar las características del conjunto. La baja concentración de algún relleno puede no ser suficiente para generar cambios, mientras que altas concentraciones pueden inhibir las propiedades de las otras [6,10].El objetivo del presente trabajo es analizar las propiedades dieléctricas y magnéticas de compuestos preparados a partir de la dispersi...
