Effect of Silica Addition on Mechanical Properties of Eggshell-Derived Hydroxyapatite

Abstract: Eggshell is a solid waste that is available in abundance but is being left unused. Eggshell containing calcium in a high amount. Calcium can be used as a precursor for hydroxyapatite (HAp). Modification of HAp with SiO2 is expected to improve its low mechanical properties for biomedical applications. In this study, HAp is synthesized from the eggshell. Then, it was modified by adding SiO2 utilizing the coprecipitation method with concentrations of 10%, 20%, 30%, and 40%, respectively. The HAp and HAp/SiO2 were… Show more

“…Cangkang telur ayam mengandung kalsium sekitar 95-97 % (Witoon, 2011;Curkovic et al, 2017). Hasil penelitian Hariani et al, (2021) telah menggunakan cangkang telur ayam untuk prekursor hidrosiapatit, yaitu senyawa yang dapat diaplikasikan untuk biomedis termasuk pasta gigi, implan gigi, tulang dll. Penggunaan CaCO3 sebagai bahan pasta gigi memiliki keuntungan karena murah, melimpah, mudah diperoleh dan memiliki kandungan kalsium yang tinggi.…”
