Claim 12:
13. A method for treating a carbon or ceramic yarn comprising forming a coating on the yarn in a reaction zone of a reactor by heating a segment of the yarn in the presence of a gas phase in a microwave field, wherein the gas phase comprises a mixture of a diluent gas and a coating precursor in the vapor state, and wherein the gas phase is formed at least by introducing the diluent gas into the reactor and mixing the introduced diluent gas with the coating precursor in the reactor before the reaction zone, wherein the yarn is moved in the reactor, and wherein the segment of yarn covered with the coating is transported to an additional treatment zone separate from the reaction zone where it undergoes a heat treatment without depositing a supplemental coating on the yarn in said additional treatment zone, the temperature imposed in the additional treatment zone being greater than or equal to 1100° C.
