1. A method for joining at least two carbon parts having a particle size lower than 10 μm, the method comprising the steps of:
a) positioning the carbon parts to be joined and a silicon element, said silicon element being inserted between said carbon parts, and b) maintaining the assembly formed in step a) cohesive under pressure and subjecting it to heating at a temperature between 1410° C. and 1500° C. under an inert atmosphere for a period of 10 minutes to 1 hour, to melt the silicon and form a joint containing at least one silicon carbide bridge at an interface of said carbon parts, and c) exposing the assembly obtained after step b) to a temperature higher than the temperature of step b) and between 1500° C. and 1750° C., for a period of 3 to 8 hours to consume all of the silicon and form a silicon carbide joint on the whole surface of the interface of said carbon parts. |
