Biomorphic silicon carbide ceramics are light, tough and high-strengt h materials with interesting biomedical appliions. The fabriion method of the biomor phic SiC is based in the infiltration of molten-Si in carbon preforms with open porosity. The fina l product is a biostructure formed by a tangle of SiC fibers. This innovative process allows the fabriion of complex shapes and the

Biomorphic silicon carbide (bioSiC) is a ceramic material obtained from natural resources with good mechanical properties, high biocompatibility, and osteoconductivity [15–17]. BioSiCs have a smart hierarchical porous microstructure (pore size distribution, pore orientation, and total porosity) widely determined by the material used as wood cellulosic preform.
The SiC ceramic developed from this route is called biomorphic silicon carbide. In recent years, properties of this ceramic have been studied extensively. The main advantages associated with this process are low cost, renewable raw material (i.e., wood), easy fabriion of complex shapes and retention of the complex hierarchical cellular structure in the ?nal product [6–11].

In biomorphic Silicon Carbide derived from radially cut wood, the initial efficiency of the filter is higher than 95%. Nevertheless, when the cut of the wood is axial, the efficiency depends on the pore size and the permeability, reaching in some cases values in the range 70-90%.
The manufacturing process of the silicon carbide ceramics is much cheaper.
The invention relates to a process for the production of a molded porous ceramic article containing β-SiC, which process comprises the following steps: the preparation of a molded article containing silicon and carbon and the subsequent pyrolysis and siliconization
The synthesis of biomorphic silicon carbide (SiC) requires two crucial processes, which are pyrolysis and silicon infiltration. In this study, the processing and characterization of silicon carbide ceramics from natural wood powders precursor was investigated by using two types of Asian wood powders, which are Kapur and Dark Red Meranti.

2010/9/1· X-ray diffractometry analysis indied that the ceramics obtained by firing above 1,650[degrees]C mainly consisted of SiC with trace amounts of elemental carbon and silicon. Recently, a new technique has been developed to prepare silicon carbide (SiC) ceramic products from natural wood, baoo, and man-made wood (wood-based panels or paper) by C-Si reaction at high …
Wood-derived ceramics and composites have been of interest in recent years due to their unique microstructures, which lead to tailorable properties. The porosity and pore size distribution of each wood type is different, which yields variations in properties in the resultant materials.
