ABSTRACT:
This invention relates to the preparation of a highly densified boron carbide ceramic body by the pyrolysis of a mixture comprising boron carbide powder and a preceramic organosilicon polymer selected from the group consisting of polysiloxanes, polysilazanes, polysilanes, metallopolysiloxanes and metallopolysilanes. Such highly densified ceramic bodies can be prepared by sintering under pressure or by utilizing a pressureless process.
