Ceramic Powder Synthesis by Spray Pyrolysis
A variety of spray pyrolysis (SP) techniques have been developed to directly produce ceramic powders from solutions. This paper reviews the current status of these processes in terms of the process… Expand
Modeling of Solid Particle Formation During Solution Aerosol Thermolysis: The Evaporation Stage
The evaporation state of solution aerosol thermolysis (SAT) was modeled to study the effect of various parameters on solid particle formation by solute precipitation. A comparison of the… Expand
Synthesis of Solid, Spherical Zirconia Particles by Spray Pyrolysis
A model is used to predict solid particle formation during spray pyrolysis by correlating droplet shrinkage before salt precipitation with its relative solution saturation. For the rapid drying… Expand
Sintering, microstructure and mechanical properties of Al2O3–Y2O3–ZrO2 (AYZ) eutectic composition ceramic microcomposites
Abstract We report on how the mechanical properties of sintered ceramics (i.e., a random mixture of equiaxed grains) with the Al 2 O 3 –Y 2 O 3 –ZrO 2 eutectic composition compare with those of… Expand
Innovative materials processing strategies: a biomimetic approach.
Many organisms construct structural ceramic (biomineral) composites from seemingly mundane materials; cell-mediated processes control both the nucleation and growth of mineral and the development of… Expand
Templated Grain Growth of Textured Piezoelectric Ceramics
Dielectric and piezoelectric properties of 〈001〉 fiber-textured 0.675Pb(Mg1/3Nb2/3)O3–0.325PbTiO3 ceramics
The 0.675Pb(Mg1/3Nb2/3)O3–0.325PbTiO3 (PMN–32.5PT) ceramic composition (with 1 wt. % excess PbO) was fiber textured in the 〈001〉 direction by the templated grain growth process using 5 vol % oriented… Expand
(Reactive) Templated Grain Growth of Textured Sodium Bismuth Titanate (Na1/2Bi1/2TiO3-BaTiO3) Ceramics—II Dielectric and Piezoelectric Properties
Abstract(Na1/2Bi1/2)TiO3-BaTiO3 (<6.5% BaTiO3) ceramics with <001>pc orientation were fabricated by Templated Grain Growth (TGG) or Reactive Templated Grain Growth (RTGG) using tabular SrTiO3… Expand

The Leidenfrost effect during spray pyrolysis of nickel oxide-gadolinia doped ceria composite thin films
Abstract NiO–Ce 0.8 Gd 0.2 O 1.9 − x (CGO) thin films were prepared by air blast spray pyrolysis with precursors containing nickel nitrate, cerium nitrate and gadolinium chloride in ethanol and a… Expand
