SÍNTESIS Y CARACTERIZACIÓN DE BIOVIDRIOS DE FOSFATO POR EL MÉTODO PIRÓLISIS DE AEROSOL EN LLAMA.

Using 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.
