Fibre-reinforced ceramic composite and method of making the same.

摘要

Compound ceramic material obtained by means of sintering under pressure from a silicon nitride powder (17) incorporating reinforcement filaments. Said reinforcement filaments are of trichites of silicon carbide and/or silicon nitride, and are between 10 and 300 microns in length and between approximately 0.1 and 0.5 of a micron in diameter, the granulometry of the powder (17) comprising between 0.1 and 0.8 of a micron, being in direct relationship with the diameter of said reinforcement filaments. Application to refractory parts.
