概要 |
Eggshell waste has been developed as a viable choice for biomaterials in bone regeneration. In this study, eggshell waste was subjected to calcination at 600°C, 700°C, 800°C and 900°C for 4 hours, res...ulting in the complete conversion of calcium carbonate (CaCO_3) into calcium oxide (CaO) powder. Using Scanning Electron Microscopy (SEM) and Image J software, mean particle size powders and hardness values via Vickers-microhardness were investigated. Notably, powder calcined at 900°C has the highest mean hardness value due to powder densifications with narrow pore size. Therefore, CaO as a source of calcium ions indicates its potential use in biomedical applications.続きを見る
