Biomorphic Silicon Carbide (BioSiC) is a reaction formed silicon carbide material obtained from silicon melt infiltration of a porous carbon preform derived from wood or wood-related precursors though high temperature pyrolysis.
2017/12/1· 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%. In this case, the presence of macropores in some of the samples

Biomorphic silicon carbide ceramics (bioSiCs) have been proposed as good candidates for clinical use as bone implants [15, 16]. Their ability for loading and releasing antibiotics with suitable release profile has been assessed [17, 18]. Antibiotic loaded
2018/10/9· Biomorphic silicon carbide ceramics are unique in their properties, preparation, and appliion. Its unique bionic material characteristics make full use of the pore structure of the biomorphic material itself, so it has the feature of multi-porosity, which makes it has reasonable mechanical characteristics and is convenient for preparation, thus effectively reducing production cost.
