Composition - Structure - Property Relationships In Strontium / Zinc Doped Glass-Ceramics., Mark Looney

Theses

Calcium silicate ceramics are amongst a group of ceramic materials currently utilised as bone graft materials. However, current calcium silicate grafts offer little therapeutic potential and poor mechanical properties. The objective of this project was to examine the composition-structure-property relationships arising from the incorporation of therapeutic ions of strontium (Sr) and zinc (Zn) into calcium silicate glass-ceramics (GC) in order to allow for healthy bone regeneration and antibacterial efficacy. Five compositions were studied with varying mole fractions of Sr and Zn. The GC’s were characterised using differential scanning calorimetry (DSC), x-ray diffraction (XRD) at room and ascending temperatures, x-ray tomography …
