1. , for connecting a method at least two carbon parts, the particle size of this carbon parts is less than 10 μ

  • m, and described method at least comprises the steps;

    A) locate described carbon parts to be connected and the silicon cell of thickness between 50 and 800 μ

    m, described element is inserted between described parts, and described carbon parts and described element form subassembly;

    B) make described subassembly keep combining under pressure, and in an inert atmosphere, at the temperature between 1410 DEG C and 1600 DEG C, heat described subassembly, form the joint containing at least one carbonization silicon bridge with melted silicon and in the interface of described parts;

    AndC) by step b) after the described subassembly that obtains be placed in be different from step b) described temperature and higher than step b) described temperature the temperature between 1500 DEG C and 1750 DEG C under, to consume the silicon of all fusings, and form silicon carbide joint on the whole surface at the interface of described carbon parts.
