Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...

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 ...

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 ...

Nanostructured calcium phosphate functionally graded materials (FGMs) with simultaneous gradients of density, phase composition, and mechanical properties were fabricated by consecutive uniaxial pressing of stoichiometric ...

The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...

The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...

The aim of the present study was to investigate the effect of ageing of mechanochemically synthesized clay and its TiO2composite on the simultaneous removal of Pb(II), Cd(II), Cu(II) and Zn(II) ions from acidic aqueous ...

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 ...

A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
