Preparation of 3D cubic ordered mesoporous bioactive glasses
3D body centered cubic ( I m 3 ¯ m ) and highly ordered mesoporous bioactive glasses (MBGs) were synthesized by evaporation-induced self-assembly (EISA) in the presence of a nonionic triblock copolymer template, EO 100PO 65EO 100 (F127). The influences of the concentration of F127, the reaction time...

100 (F127). The influences of the concentration of F127, the reaction time, the heat-treated temperature, and the composition on the formation of the 3D cubic ordered MBGs were investigated. The 3D cubic MBGs have a large specific surface area (∼520

−1) with uniformly distributed pore size (5.4
nm). The formation of a long-range cubic mesostructure largely depends on the concentrations of F127 and CaO. The 3D cubic structure of the MBG shows relatively good thermal structural stability up to 800
°C because of the compositional homogeneity.
