Preparation of ZrO2 and ZrO2/SiC powders by carbothermal reduction of ZrSiO4
(Journal of Alloys and Compounds, 2011)
This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ...
Kinetic study of isothermal crystallization process of Gd2Ti2O7 precursors powder prepared through the Pechini synthetic approach
(Journal of Physics and Chemistry of Solids, 2015)
Crystallization process of Gd2Ti2O7 precursors powder prepared by Pechini-type polymerized complex route has been studied under isothermal experimental conditions in an air atmosphere. It was found that the crystallization ...
Influence of MgO addition on the synthesis and electrical properties of sintered zinc-titanate ceramics
(Journal of Alloys and Compounds, 2009)
Starting mixtures of ZnO, TiO(2) and MgO (0, 1.25 and 2.5 wt.% MgO) powders were mechanically activated for 15 min in a planetary ball mill. The powders obtained were sintered non-isothermally to temperatures between 800 ...
Influence of Mechanical Activation on Microstructure and Crystal Structure of Sintered MgO-TiO2 System
(Science of Sintering, 2010)
Mixtures of MgO-TiO2 were mechanically activated using high-energy planetary ball mill during 5, 10, 20, 40, 80 and 120 minutes. Sintering process was preformed in air at 1100 degrees-1400 degrees C for 2h. The decrease ...
Synthesis of Barium-zinc-titanate Ceramics
(Science of Sintering, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
Sol-gel synthesis and characterization of iron doped mullite
(Journal of Alloys and Compounds, 2014)
Amorphous powders of iron doped 3:2 mullite (3Al(2)O(3)center dot 2SiO(2)) were prepared by sol-gel combustion process using ethanol-water solutions of Al(III) nitrate, Fe(III) nitrate, TEOS and urea. Compositions up to ...
