Title: Fabrication of a new porous glass-ceramic monolith using vanadium(III) calcium phosphate glass as precursor
Author: Mazali, Italo Odone
Alves, Oswaldo Luiz
Abstract: Preliminary XRD, IR, Raman and SEM data indicate that porous glass-ceramic monoliths (pgc-LVCP) with skeleton of V(PO3)3 and Ca3(VO4)2 with three-dimensional network structure using an original Li2O-V2O3-CaO-P 2O5 glass as precursor was obtained. The pgc-LVCP is a promising porous host for integrated chemical systems because the Ca3(VO4)2 has ferroelectric and luminophor properties while V(PO3)3 exhibits magnetic properties associated with high degree of mechanical, chemical and thermal stability.
Resultados preliminares de XRD, IR, Raman e SEM mostraram que monólitos vitrocerâmicos porosos (pgc-LVCP) com esqueleto tridimensional constituído pelas fases V(PO3)3 e Ca3(VO4)2 foram obtidos utilizando um vidro original de Li2O-V2O3-CaO-P 2O5 como precursor. O pgc-LVCP pode ser um hospedeiro poroso promissor para sistemas químicos integrados visto que a fase Ca3(VO4)2 apresenta propriedades ferroelétricas e de luminescência enquanto a fase V(PO3)3 exibe propriedades magnéticas associadas com elevada estabilidade mecânica, química e térmica.
