Notes:
Towards the design of bioceramics with control over both macroscopic shape and mesoporosity,silica based mesoporous materials have been synthesized using evaporation-induced self-assemblymethod by two different routes: room temperature (RT) and aerosol-assisted synthesis (A-A). Twoseries varying surfactant/silica precursor ratio have been synthesized in order to check the mesoporeordering as a function of the structure directing agent amount in both preparation procedures. TheA-A method leads to spherical microparticles, which exhibit mesopore ordering for a widersurfactant/silica range compared with room temperature method, which yield irregular shapedparticles. Textural properties values show that for the same surfactant amount, aerosol-assistedmethod develops higher porosity values in the obtained silica microparticles
