Synthesis and Microstructure CaTiO3 coating by Sol-Gel Spin-Coating Process

Abstract

Recently, Calcium Titanate has been introduced as a bioactive bioceramic with acceptable mechanical and better biological properties compared to hydroxyapatite for orthopaedic implant applications.  In this study, CaTiO₃ nano-structure coating was produced by sol-gel spin-coating route for biomedical applications. Calcium oxide and titanium isopropoxide were used as a precursor for the sol-gel spin-coating. After coating process, the specimen was subjected to heating in oven at 100^oC for 24 hours and the sample was heated at 800°C for 2 hours. The phase structure and surface morphology of coating were investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Finally, it concluded that the uniform crack-free nano-structured CaTiO₃ coatings could be used for the biomedical application.
