Keywords: calcium silicate, bio nanoparticles, egg-shell and sonochemical method


Due to the high cost and environmental hazard of the petroleum and mineral derived products, a growing effort has emerged in recent years on the research, development, and application of bio-composites materials for engineering applications. Chicken eggshell is an industrial byproduct that has been considered as one of the worst environmental hazard, however it can offer a great material for industrial and structural applications. Eggshell contains about 95% calcium carbonate in the form of calcite. In this study the chicken Egg shells were used as source of calcium carbonate and calcium oxide. The mechanochemical and sonochemical process were developed to reduce the particle sizes of chicken egg shell and used for the synthesis of calcium silicate nanoparticles. The as-prepared materials were characterized using XRD, TEM and EDS techniques.
