The aim of this work is to synthesize a net of interwoven β-Si3N4 nanofibers and intertwined pea-pods and hand-fan like Si2N2O nanostructures by the chemical vapor deposition (CVD) method at a relatively low temperature (1300°C) and short times (up to 4h). A solid precursor (Na2SiF6) was thermally decomposed at 400°C into two new products: 2NaF and SiF4. Afterwards, the SiF4 reacts with a flow of...
Sea-urchin-like rutile (su-TiO2) microstructures were successfully synthesized by thermal decomposition and oxidation of a solid precursor, K2TiF6. During the synthesis, precursor temperature (640°C), N2-flow (15cm3/min) and inner pressure (90mbar above the atmospheric pressure) remained constant. In order to evaluate the effect of time on the morphology of su-TiO2, five levels (0.5, 1, 1.5, 2, and...
