Fabrication of Calcium Phosphate Bioceramics by Using Bovine Bone: Bioceramics,Used
Delivery time: 8-12 business days (International)
Bovine bone procured from the slaughterhouse was deproteinated by sintering method intended for the usage of bone graft substitute. The effect of sintering was investigated by thermal analysis, scanning electron microstructure (SEM) and physicochemical methods such as xray diffraction (XRD), energy dispersive xray spectroscopy (EDX) and Fourier transformed infrared spectroscopy (FTIR). The XRD results revealed that the process of sintering promoted the crystallinity of bone samples, particularly at temperatures of 700C, 800C, 900C and 1000C. There was no secondary phase transformation detected for sintered bone at these temperatures except the presence of the hydroxyapatite (HAp) phase. Decomposition of HAp to betatricalcium phosphate (TCP) was observed when sintered at temperatures 1100C and 1200C for 2 hours. The FTIR spectra of raw bovine bone indicated the presence of organic macromolecules. However these organic macromolecules were not available in the samples sintered at temperatures 600C and above.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
