Synthesis and characterization of hydroxyapatite/silica composites based on cockle shells waste and tin tailings

Abstract

Hydroxyapatite is a biocompatible material that has great potential in the development of scaffold in the bone tissue engineering. To satisfy the needs of mechanical properties and the time of degradation to support the bone growth, currently hydroxyapatite-based composite material is being developed. One of the fillers that can be used is silica because it also has excellent biocompatible properties. In this study, hydroxyapatite/silica composites were prepared using cockle shell waste and tin tailings as raw materials. The study aims to utilize the waste produced in the maritime and mining sectors to move towards sustainable industries. The characteristics observed in this study are crystal characteristics and degradation properties of composites.
