Abstract

Diopside was prepared sintering a powder compact of composition CaMgSi2O6 at 1573K for 2 hours. The bending strength of this sintered body was 300MPa and fracture toughness was 3.5MPam1/2. Diopside was soaked in a simulated body fluid at 309.5K. Three days later diopside formed hydroxyapatite (Hap) all over the surface [1]. Diopside implanted in rabbits came in close contact with the newly grown bone. EPMA spectral diagrams show a change of composition across the junction from the diopside to the newly grown bone [2].
