Effects of mechanical activation and two-step sintering on the structure and electrical properties of cordierite-based ceramics
The mechanical activation can help reduce production costs and modify cordierite-based materials. In this study, the structure and electrical properties of the mechanically activated MgO-Al2O3-SiO2 system have been analyzed. ...
Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
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 ...
Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
Starting nanopowders of TiO2 (anatase 99.7%) and α-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750–1250 °C in air. Structural, morphological and ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources – talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Microstructure and dielectric properties of Dy/Mn doped BaTiO3 ceramics
Dy/Mn doped BaTiO3 with different Dy2O3 contents, ranging from 0.1 to 5.0 at% Dy, were investigated regarding their microstructural and dielectric characteristics. The content of 0.05 at% Mn was constant in all the ...
