1989/9/26· The SiC sheaths of these fibers have thermal, chemical, and mechanical properties that more closely approximate those of bulk stoichiometric silicon carbide than do PD silicon carbide fibers. The outer surface of these fibers is then coated predominantly with pyrolytic carbon; the coating probably also includes some silicon carbide.
Silicon carbide wafers, substrates polished from Valley Silicon Carbide (SiC) Polished to Mirror Finish CVD Silicon Carbide theoretically dense and intrinsically pure, is available as lapped or polished substrates and wafers from 2" diameter up to 300mm diameter with surface finishes to better than 10 angstroms, while maintaining a 1/4 wave flatness depending on thickness and size.
The silicon carbide fiber has the same form as the carbon fiber, and the dimensions of the silicon carbide fiber and the carbon fiber are essentially unchanged. Silicon carbide fiber produced from unactivated, non-porous carbon fiber having specific surface areas lower than 100 m 2 /g remained unreacted at the core.

2014/9/4· Silicon carbide (SiC) is widely used in many fields due to its unique properties. Bulk SiC normally has a flexural strength of 500 - 550 MPa, a Vickers hardness of ~27 GPa, a Young''s modulus of 380 - 430 GPa, and a thermal conductivity of approximately 120 W/mK. SiC fibers are of great interest since they are the good candidates for reinforcing ceramic matrix composites (CMCs) because of the
Silicon carbide fibers, where the basic polymers are not hydrocarbons but polymers, where about 50% of the carbon atoms are replaced by silicon atoms, so-called poly-carbo-silanes. The pyrolysis yields an amorphous silicon carbide, including mostly other elements like oxygen, titanium, or aluminium, but with mechanical properties very similar to those of carbon fibers.
