Overview of the use of the sol-gel method in the synthesis and analysis of hydroxyapatide from biowaste

Abstract

Abstract The aim of this review was to determine the synthesis of hydroxyapatite biomaterial from bone waste by sol-gel method. The sol gel method was chosen because it can operate at low temperatures, simple method, inexpensive. Waste materials were used in the study since it is currently uncommon to synthesize bone implant hydroxyapatite using waste resources. Additionally, using waste products to create hydroxyapatite is a great way to help Indonesia reduce its waste production. Moreover, this review revealed the biowaste which excellent potential as the source of hydroxyapatite. As well as in this review it was found that heating the sample at 1000°C is necessary to synthesize pure hydroxyapatite, and the resulting material has unique characteristics as shown by XRD and FTIR patterns.
