What Types of Bioceramics ??

**Ceramics used in biomedical application..

Alumina: Al₂O_{3  (bioinert)}

          Zirconia: ZrO<sub>2  

     Pyrolytic carbon

     Bioglass

     Tricalcicum phosphate:</sub> Ca₃(PO₄)<sub>2



 What is mechanical properties of ceramic 


biomaterials??



     Young's modulus:Alumina=380, Bio-


Glass ceramics=22, Calcium 


phosphates=40-17, Pyrolytic carbon=18-


28.






    Compressive strength: Alumina=4500, 


Bio-Glass ceramics=500, Calcium 


phosphates= 510-896, Pyrolytic 


carbon=517</sub>



** Nonabsorbable or somewhat Bioinert
