Investigation of merwinite/wollastonite prepared by sol-gel metod

Abstract

Abstract<br><br>Silicate bioceramics have attracted too much attention as a new family of biomaterials in hard<br><br>tissue regeneration applications. Investigation have shown that novel bioceramics sush as<br><br>merwinite and wollastonite perform better than Hydroxyapatite in repairing bone tissue and<br><br>possess better mechanical and bioactivity properties In this study , merwinte and wallestonite<br><br>based on Cao , Mgo , Sio2 that have recently been known as bioactive bioceramics , were<br><br>syntherized via a sol-gel approache and calcined in varions temperatures.<br><br>Phase analysis were investigated and characterized using XRD , SEM. The results of xrd<br><br>confirm the formation of pure merwinite and wollastonite with grain size of aboute 16,72 nm<br><br>respectively. Regaeding all the obtained results , it can be noticed that merwinite and<br><br>wollastonite bioceramics having Ca , Mg , and Si can be used az new and promising<br><br>biomaterials in bone tissue repairing applications. Thse bioceramics have a wide range of<br><br>aplications in the filds of tissue engineering and repairing diseased tissues due to their unique<br><br>properties like bio compatibility , bio degradability non toxicity and their stability in body`s<br><br>physiological environment
