Abstract

Promoting sustainable living in the future involves efficiently managing waste to reclaim resources and convert them into new raw materials. There is a global focus on accelerating the utilization and recycling of waste to create valuable biomaterials, driving significant research efforts in this area. In this research, pure silica was isolated from glass waste and used in the manufacture of a type of bioceramic for medical applications. Several sequential stages were followed, starting with collecting samples of crushed glass and treating them physically (grinding, granular sorting), mixing the ground glass with NaOH in the following proportions (1 :1), (2:1) (3:1), then heat treatment was carried out at different temperatures (1000-900-800), then the silica was isolated by treating the sample with HCl solution, followed by heat treatment at 900 degrees to obtain SiO2 with a yield of 68% and purity reaches 99.4%. Isolated pure silica was used to prepare standard bioglass 45S5.

Specifications of prepared bioglass was determined using XRD, IR, and DTA, then the bioglass was converted into bioceramic through heat treatment according to DTA to ultimately obtain a product whose properties, composition, and susceptibility to biodegradation were studied, results indicate that it was usable in medical applications.
