Bioactive glasses have been used for many years in the human body as bone substitute Since bioactive glasses are not readily available in the form of endless thin fibres with diameters below 20 µm their use is limited to mainly non load bearing applications in the form of particles or granules In this study the spinnability of four bioactive silicate glasses was evaluated in terms of
