With increasing of the world energy crisis, research for new, renewable and alternative energy sources are in growth. The focus is on research areas, sometimes of minor importance and applications, where the different ...

The structure of BaTiO3 based materials can be controlled by using different technological parameters and different additives. In this paper, microstructure and dielectrical properties of Er2O3 doped BaTiO3-ceramics, ...

Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...

Cordierite-based ceramic materials are attracting much interest for their various applications in industry, for manufacturing multilayer circuit boards, catalytic converters, filters, thermal insulation, kiln furniture, ...

The nickel and cobalt disperse alloy deposits of five different compositions were obtained by electrodeposition on Cu substrates in the galvanostatic regime from an ammonium sulfate-chloride solution. The effect of cathodic ...

A new approach, based on fractal geometry and correlation between microstructure-nanostructure and rare-earth properties and other additives doped BaTiO3-ceramics and electronics properties, is applied. The grain contacts ...

Structural changes caused by mechanical activation of SrTiO3 powders were investigated using a variety of methods. Average crystallite size continuously decreased with increased activation time to around 20 nm after 120 ...

The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...

Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...

Nanostructured single layered (pure TiO2 , pure α-Fe2O3 and mixed Fe2O3 /TiO2 with two different oxide ratios, 2 : 3 and 3 : 2) and double layered (TiO2 layer over a Fe2O3 layer) thick films have been fabricated by screen ...
