ABSTRACT:
A process is provided that involves reductive coupling of polysilane precursors to form polysilane in the presence of ultrasonification. The resulting precursors, upon pyrolysis, lead to improved SiC ceramic product. Ultrasonification can be used to produce oligosilanes from precursors thereof, or polysilanes from monomers, dimers, trimers, or oligomers. Precursors can include Si:C in a ratio of about 1:1, and the invention allows formation of SiC having a Si:C ratio of about 1:1.
