Model of charge partial, polimerization, sol-gel, watery dissolution, solid phaseAbstract
In the present work we studied the chemical reactivity of cations Fe (III) and W (VI) in watery dissolution ,besides we propose the involved mechanism of reaction in the
chemical process until the obtaining of the solid phase. The chemical reactions involved in the middle watery were studied using the Model of Charge Partial (MCP) who
describes to the hydrolysis and condensation of cations Fe(III) and W(VI) dissolved in water and the chemical species that form when connecting with links H,O, OH and
0₂. The polymerization sol-gel, as well as the formation of the solid phase until the obtaining of oxide of iron and tungsten oxide were studied by the techniques of Visible
Spectroscopy, Dispersion of Light, Infrared Spectroscopy, Transmission Electronic Microscopy and X-ray Diffraction. It were determined that the solid phases of the W(VI) and Fe (III) to 500 °C were monoclinic WO, and a-Fe.O, hematite respectively.
