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 ...
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 ...
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 ...
