Microwave assisted hydrothermal synthesis of (Fe,Co) 3 O 4 nanoparticles in the presence of surfactants and effects of Co/Fe ratio on microstructure and magnetism
(Ceramics International, 2018)
Microstructure and magnetic properties of nanoparticles can be tailored by optimising the synthesis procedure and changing chemical composition. In this study, a two-step procedure, i.e., coprecipitation in the presence ...
Niobium and zinc doped titanium-tin-oxide solid-solution ceramics: Synthesis, structure and electrical characterization
(Ceramics International, 2018)
This paper describes the processing, microstructure, optical and electrical properties of the nanocrystalline (NC) niobium and zinc doped titanium-tin-oxide (TTO:NZ) based ceramics. Variety of techniques was employed (X-ray ...
Cyclic oxidation of Ti3Al-based materials
(Ceramics International, 2019)
The microstructure variation and oxidation behavior of a hot-rolled and quenched Ti-24Al-11Nb (at%) intermetallic alloy with and without protective Ni-20Cr (at%) coating were studied in the air at a cyclic annealing ...
Improved coloristic properties and high NIR reflectance of environment-friendly yellow pigments based on bismuth vanadate
(Ceramics International, 2018)
Herein, fine powders of yellow pigments based on BiVO4 were successfully prepared in two crystalline forms, tetragonal zircon-structured and monoclinic scheelite-structured, through a ethylene glycol-assisted method subjected ...
Shape and aspect ratio analysis of anisotropic magnetic nanochains based on TEM micrographs
(Ceramics International, 2018)
Due to advances in electron microscopy and to the development of novel nanoparticle structures with different morphologies and the dependence of physical properties on the nanoparticle morphology, there is a need for a ...
Observation of low- and high-temperature CuFe2O4 phase at 1100 °C: The influence of Fe3+ ions on CuFe2O4 structural transformation
(Ceramics International, 2018)
Samples containing CuFe2O4 and CuO nanoparticles were synthesized by coprecipitation method and subjected to thermal treatment at 300 °C, 500 °C, 700 °C, 900 °C and 1100 °C. Depending on the synthesis conditions, ...
Magnetic properties of mesoporous hematite/alumina nanocomposite and evaluation for biomedical applications
(Ceramics International, 2021)
A porous hematite/alumina nanocomposite is produced by sol-gel combustion synthesis. The XRPD, Raman and FTIR methods show the presence of α-Fe2O3 phase while SEM, TEM, EDS and BET techniques further reveal the formation ...
Effect of YAG content on creep resistance and mechanical properties of Al2O3-YAG composite
(Ceramics International, 2020)
Comprehensive study on effect of YAG amount on densification, creep resistance and room-temperature mechanical properties of Al2O3-YAG composite pressureless sintered at 1600 degrees C was conducted. The main goal was to ...
Novel cordierite-acicular mullite composite for diesel particulate filters
(Ceramics International, 2021)
Cordierite-acicular mullite composites containing 0, 25, 50, 75 and 100 wt% of mullite were fabricated from waste MoSi2 and commercial powders of Al2O3 and spinel (MgAl2O4). Careful oxidation of pulverised waste MoSi2 ...
Structural and morphological characterization of iron-doped sol-gel derived mullite powders
(Ceramics International, 2020)
The structural and morphological properties of iron-doped mullite powders are the subject of the present study. The powders of undoped and iron-doped mullite in the composition range of 3–15 wt% Fe2O3 were synthesized by ...
