Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
(Elsevier, 2014)
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 ...
Investigation of sintering kinetics of ZnO by observing reduction of the specific surface area
(Belgrade : International Institute for the Science of Sintering, 2007)
Reduction of the specific surface area of porous ZnO during the sintering process was studied. ZnO powder was sintered at temperatures from 673 K to 1173 K. The decrease in the specific surface area was observed as a ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Belgrade : International Institute for the Science of Sintering, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Elsevier, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and α-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of γ to α phase transformation mechanism
(Elsevier, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Fractal nature Heywang model contribution and BaTiO3-ceramics semiconducting phenomena
(Belgrade : Serbian Ceramic Society, 2018)
Well known material with ferroelectric properties, BaTiO3-ceramics, have many advanced applications. Fractal approach in analyzing of these structures can be one of the solution for investigation of morphology. It is known ...
The influence of powder characteristics on two-step sintering behavior of hydroxyapatite
(Belgrade : Institute of Technical Sciences of SASA, 2010)
Fabrication of full dense ceramic materials on the basis of hydroxyapatite (HAp) and biphasic calcium phosphate (BCP) with controllable microstructural and compositional characteristics attracts considerable efforts. Various ...
Barium-zinc-titanate ceramics
(Kiev : National Academy of Sciences of Ukraine (NASU); Frantsevych Institute for Problems of Materials Science of NASU; National Technical University of Ukraine "KPI"; Ukrainian Materials Science Society; INTEM LTD, 2010)
Starting mixtures of BaCO3, ZnO and TiO2 powders were mechanically activated in a planetary ball mill for various periods of time. The powders obtained were sintered nonisothermally to temperatures between 1100 and 1300°C ...
