The Influences of the Heat-Treated Temperature on Mesoporous Bioactive Gel Glasses Scaffold in the CaO — SiO2 — P2O5 System

Abstract

Mesoporous bioactive glasses (MBGs) have been successfully synthesized by templating with a block copolymer. The specific surface area and crystallite size of mesoporous bioactive gel glasses scaffold calcined at different temperature are evaluated. The phase structure, N2 adsorption/desorption isotherm and powder morphology were analyzed by XRD, BET and FE-SEM. The influences of the heat-treated temperature on pore morphology and specific surface area of the cubic ordered MBGs Scaffold were very important. High Specific Surface area Mesoporous Bioactive Glasses (MBGs) scaffold successful fabricated by calcined the coprecipitated dry gel at 500°C and dwell 2h. After soaking these MBGs scaffolds in simulated body fluid (SBF) for 24 h, it can be observed that the formation of needle shape hydroxylapatite (HAP) crystal on the surface of the MBG scaffolds.
