Synthesis and degradation properties of β-TCP/BG porous composite materials

Abstract

β-TCP/BG porous composite materials were successfully fabricated by foaming technology. X-ray diffraction was used to determine the crystal structure of powders. The pore size and distribution of the resulting materials were characterized using scanning electron microscopy. The porosity and degradation performance of materials were also investigated. The results showed that the porous composite materials possessed the pore size ranging from 100 to 500 μm in diameter, whereas the interconnection among macrospores was poor. The porosity in materials increased from 58·7% to 63·47% with BG content ranging from 0 to 3 wt%, further increasing of BG content results in a decrease in porosity. The degradation rate of composite materials can be adjusted by varying the BG content. © Indian Academy of Sciences.
