The scope of this work was observing dimensional and heat transfer changes in ZnTiO3 samples during heating in nitrogen and air atmosphere. Interactions of bulk specimens with gaseous surrounding induce microstructure ...

Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...

The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...

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 ...

Commercial Mn-Zn powder (Mn0.63Zn0.37Fe2O4, 93 wt. % and Fe2O3 7 wt. %) was milled 0.5, 1, 2 and 4 hours in a planetary ball mill. The goal was to observe intensive milling influences on oxidation and reduction processes ...

BaTi1-xSnxO3 (BTS) powders, with x ranging from 0 to 0.15, were synthesized by solid-state reaction technique. The powders were pressed and sintered at 1370 degrees C. Obtained BTS ceramics were investigated by X-ray ...

The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...

In this study, porous macro- and micro-cellular wollastonite-based ceramics was synthesized. A ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as a starting material. After 20 min of ...

Hydroxyapatite nanopowders have been widely studied for biomedical application due to excellent biocompatibility. It attaches chemically to bone tissue providing fixation of artificial implant materials. Main research ...

Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400ºC). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier ...
