Abstract: This project addresses the development of new materials in the form of vitreous microspheres, prepared via flame synthesis, and their utilization in 3D glass and glass-ceramic structures. The project focuses on the optimization of the flame synthesis parameters (i.e. the length vs temperature of flame ratio, the red-ox conditions of ignition, or the precursor feeding rate). These conditions influence the chemistry, structure, and morphology of synthesized microspheres. Full, hollow and porous microspheres will be prepared in aluminate, silicate, borate and boro-silicate systems, which, in many cases such compositions are difficult to achieve via conventional glass-making methods. Hollow and porous microspheres will be prepared via alkali activation or the addition of porogens. Microspheres will be used for the preparation of advanced 3D structures via the Additive Manufacturing Technology (3D print), which utilizes Direct Light Processing, Direct Ink Writing and Hot Isostatic pressing.
