Fractal frontiers in microelectronic ceramic materials
The world's perennial need for energy and microelectronic miniaturization brings with it a broad set of technological and scientific challenges. Materials characterized by precise microstructural architectures based on ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...

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 ...
The use of various dicarboxylic acids as a carbon source for the preparation of LiFePO4/C composite
(Ceramics International, 2015)
Olivine-type LiFePO4 composite powders with carbon were synthesized by freeze drying and subsequent thermal annealing. The main purpose of the research is to explore how various dicarboxylic acids as carbon sources influence ...
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 ...
Y2O3:Yb,Tm and Y2O3:Yb,Ho powders for low-temperature thermometry based on up-conversion fluorescence
Recently, trivalent rare earth doped materials have received significant attention due to the strong temperature dependence of the fluorescence emission of these materials, which can be useful in temperature sensing. Here, ...
Preparation and properties of porous, biomorphic, ceria ceramics for immobilization of Sr isotopes
A new technology for radionuclide trapping which is based on bio-templating approach was proposed in this paper. Porous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium ...
Optimization of the production process through response surface method: Bricks made of loess
Loess clays are commonly used to produce bricks. Heavy clays, taken at location near Zrenjanin, Serbia, are used as a representative raw material in this study. The sample, containing about 28% of clay sized particles, is ...
Structural and chemical properties of thermally treated geopolymer samples
This article presents the results of the compositional, structural and morphological study of geopolymers synthesized from metakaolin and an alkali activator. The study involved the investigation of the structural and ...
