dc.descriptionUsing the novel flame aerosol pyrolysis method (FSP), a calcium phosphate bioglass was synthesized for the first time in the P2O5-CaO-Na2O. The samples obtained were characterized by X-ray diffraction(XRD) and diffuse reflectance infrared spectroscopy (DRIFTS), the latter serving to follow in-vitro biomineralization kinetics for 15 days in simulated body fluid (SBF). Using XRD, the amorphous nature of the bioglass was validated by exhibiting the whitlockite phase.The DRIFTS analysis revealed the characteristic bands of the phosphate groups in a range of about 500 to 1400 cm-1. Respectively, the evolution of the phosphate bands in the samples submerged in SBF indicate the formation of apatite, a process that followed a pseudo-first-order Lagergren kinetics.en-US
dc.descriptionEmpleando el novedoso método pirólisis de aerosol en llama (FSP) se sintetizó por primera vez un biovidrio de fosfato de calcio en el sistema P2O5-CaO-Na2O. Las muestras obtenidas se caracterizaron mediante difracción de rayos X (DRX) y espectroscopía infrarroja de reflectancia difusa  (DRIFTS), sirviendo esta última para seguir la cinética de biomineralización in-vitro durante 15 días en fluido corporal simulado (SBF). Mediante DRX se validó la naturaleza amorfa del biovidrio exhibiendo la fase whitlockita. El análisis DRIFTS reveló las bandas características de los grupos fosfatos en un rango de alrededor de los 500 a 1400 cm-1. Respectivamente, la evolución de las bandas de fosfatos en las muestras sumergidas en SBF indican la formación de apatita, proceso que siguió una cinética de pseudo- primer-orden de Lagergren.
