sintered ceramics
The sintered ceramics of those powders doped by Sr2+ and Zr4+ or Zn2+ and Sn4+ have dielectric constant twelve times higher than and dielectric loss 1/6 those of pure BaTiO3 phase at room temperature.
      
Combustion in fluorine offers a new method for the fast decomposition of several ceramic powders and sintered ceramics.
      
It is well known that sintered ceramics are very hard and difficult materials to process and machine by traditional methods.
      
The effects of sintering temperature on the density, microstructure, and dielectric properties of the sintered ceramics were investigated.
      
The aim of this study is to investigate the mechanisms of the dielectric enhancement based on the unique structural and morphological properties of the laser-sintered ceramics.
      
The reason for the dielectric enhancement is due to the crystal structure distortion in the high-temperature phase, the oriented grain growth taking place in a direction deviating from [001] in the laser-sintered ceramics.
      
Lanthanum-modified lead zirconate titanate (PZT) powder and volatilisable polymethylmethacrylate (PMM) polymer particles have been used for fabrication of porous sintered ceramics of interconnected porosity varying from 25% to 59%.
      
Sintered ceramics are converted into piezoelectric PZT-polymer composites by incorporating silicone rubber elastomer followed by electroding and poling.
      
The dense sintered ceramics fabricated using these powders were characterized for their microstructure, crystallite size and phase composition.
      
The flexural strength, fracture toughness and microhardness of sintered ceramics were measured.
      
Surprisingly, the sintered ceramics of this oxide worked as a cathode without mixing with a conductive powder such as graphite.
      
The preliminary results show higher percentage of carbon on the surface in comparison to the core of the sintered ceramics, indicating the existence of carbon contamination on the surface, possibly caused by the sintering process itself.
      
The thermal conductivity of refractory powders and sintered ceramics
      
The use of powders dispersed by the explosion method markedly improves the properties of sintered ceramics.
      
The formation specifics of the structure and phase composition of densely sintered ceramics based on a low-melting argillaceous material from Belarus together with a combined flux and a grog additive are investigated.
      
The phase transformation and microwave dielectric properties of sintered ceramics were investigated using the X-ray powder diffraction (XRD) and a network analyzer, respectively.
      
A minor phase in sintered ceramics is the 15R "polytype" of the AlN structure.
      
A minor phase in sintered ceramics is the 15R "polytype" of the AlN structure.
      
Sintered ceramics were evaluated for their microstructure and electromechanical properties.
      
We have shown thatm has a value of nearly 2 for sintered ceramics, unless sintering aids or hot pressing have been used during fabrication of the ceramic.
