| 摘要 |
This invention relates to the preparation of highly densified ceramic bodies by the pyrolysis of a mixture comprising a preceramic organopolysiloxane, alpha silicon carbide powder, a source of boron, a source of aluminum and, optionally, a curing agent for the organopolysiloxane. Such highly densified ceramic bodies are prepared by sintering under pressure or by a pressureless sintering process. |
