Patent

CA 1335016

The preparation of highly densified ceramic bodies by the sintering of certain polysilanes filled with silicon carbide powders, metal-containing sintering aids and, optionally, polysilane curing agents is described. Such highly densified ceramic bodies can be prepared by either a pressureless sintering process or a hot press sintering process. The compositions of this invention can be formed into desired shapes and then sintered to form ceramic, shaped bodies with high densities. One advantage of the present invention is that the green bodies have relatively high strengths and thus can be easily handled and, if desired, machined before being sintered. The polysilanes useful in this invention must yield a ceramic char which contains free or excess carbon in addition to carbon in the form of silicon carbide upon pyrolysis to elevated temperatures.
