Opis:
Nano-size β-tricalcium phosphate powders with average grain size of 80 nm were prepared by the wet chemical precipitation method with calcium nitrate and di-ammonium hydrogen phosphate as calcium and phosphorus precursors, respectively. The precipitation process employed was also found to be suitable for the production of sub-micrometre β-TCP powder in situ. The sinterability of the nano-size powders, and the microstructure, mechanical strength of the prepared β-TCP bioceramics were investigated. Bioceramic sample characterization was achieved by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR), and density measurements. Powders compacted and sintered at 800, 900, 1000 and 1100 °C showed an increase in relative density from 70 % to 93 %. The results revealed that the maximum hardness of 240 HV was obtained for β-TCP sintered at 1100 °C.

Opis:
In light of recent events in the replacement and generation of human tissues, it is becoming extremely difficult to ignore the existence of bioceramics. Although hydroxyapatite and betatricalcium phosphate materials are frequently employed individually, they both lack certain qualities. As a result, combining hydroxyapatite and beta-tricalcium phosphate may result in the combination of their respective qualities. The current study aims to investigate the effect of using a novel nanostructure called silicene (silicon nanosheet-SiNS) on the mechanical properties of the composite ceramic (biphasic calcium p hosphate) at various ratios of hydroxyapatite and beta-tricalcium phosphate. The silicene has been synthesized and added at different weight percentages of 1, 3, and 5%. The results reveal that the compressive strength improved due to increasing the content of silicene. The average of increasing was between 58.6% and 142% because of the strong hexagonal structure of silicene. At the same time, the hardness of the biphasic calcium phosphate composite was enhanced by increasing the weight percentage of silicene. However, the hardness decreased when the content of silicene was more than 3% due to the presence of small cavities on the surface of the samples.
