Resumo: This paper shows the determination of the most energy efficient composition for molding of bioglasses in the SiO2 -Na2O-CaO-P2O5 system. Ten compositions were formulated in the range where the glass has a bioactivity index greater than 8 and the curves of viscosity as a function of temperature were drawn using the Vogel-Fulcher-Tammann (VFT) equation. Analyzing the curves, the composition 43SiO2 -30CaO-21Na2O-6P2O5 has the lowest viscosity over the entire working temperature range, requiring less heat to be molded and consequently consuming less energy in the ovens.
