COXSIYTEZ NANOCOMPOSITE MANUFACTURE BY SOLUTION COMBUSTION PROCESS ASSISTED BY MICRO-WAVE

A possible formation of the nanocomposite based on silicon, cobalt and tellurium was produced by the combustion synthesis process in solution (SCS) assisted by microwave in two stages, combustion using a conventional microwave oven and purification by means of calcination at 650 ºC in a muffle furnace. The new material was developed in different oxidant-fuel relationships where it observed the effects on the evolution of the phase and morphology of the powders, the structural, morphological and thermal properties were investigated by the X-ray diffraction technique (XRD), energy dispersive X-ray spectroscopy (EDX) coupled to the scanning electron microscope (SEM) and TGA and DTG curves. Through the analysis it is possible to suggest the development of a new stable material in single phase, being isostructural to the Co₈Te₁₂O₃₂ (ICDD-50702) of nanometric dimensions with interesting potentials due to the properties of the constituent elements.
