Developing Highly Porous Glass Microspheres via a Single-Stage Flame Spheroidisation Process

Abstract Glass microspheres are gaining attention in bone tissue engineering due to their ability convert into hydroxyapatite-like materials, resembling the inorganic mineral of natural bone. The morphology glass as starting material has been considered influence conversion rate and resulting product where porous could promote faster hydroxyapatite than solid microspheres. This paper reports on manufacturing (solid porous) using a flame spheroidisation process. effect various gas ratios acetylene oxygen morphological changes was investigated. Irregular shaped particles with particle size ranges 63 – 125 μm were used feed delivered hot produce To manufacture via single-stage process, calcium carbonate utilised porogen mixed particles. Solid successfully produced, exploring 3:3, 4:7, 5:7 6:7 mean range between 73 105 μm. Moreover, average pore 6 9 obtained ratios, respectively. process is promising method for producing both bioactive
