제목 | Synthesis and characterization of tricalcium phosphate substituted withmagnesium and zinc |
초록 | Among calcium phosphate ceramics, tricalcium phosphate (Ca3(PO4)2, TCP) is one of interesting materials for orthopedic and dental applications due to their excellent biocompatibility and osteointegration properties. According to the sintering temperature, TCP exist in three crystal phases such as β-TCP(below 1125oC), α-TCP(between 1125 and 1430oC), and α’-TCP(above 1430oC). Among these phases, mainly β phase is used as biomedical applications. However, β-TCP has poor mechanical properties due to its insufficient compaction from sintering below the β- to α- transformation temperature(1125oC). Some additives enhance structural stability and consequently improvement of the thermal stability of β-TCP. Spray pyrolysis process has a lot of advantages such as preparation of droplet including homogeneous composition component, pure homogeneity, fast reaction time, and so on. In this work, β-TCP substituted with magnesium and zinc used as sintering additive was synthesized via spray pyrolysis. Magnesium and zinc was added up to 16mol%. The synthesized particle was investigated using XRD, SEM and TG-DSC. |
