摘要： The invention concerns a method for producing a ceramic material, the method comprising the following step: forming a ceramic material by implementing a first chemical reaction at least between a first powder of an intermetallic compound and a reactive gas phase, a liquid phase being present around the grains of the first powder during the first chemical reaction, said liquid phase being obtained from a second powder of a metal compound by melting the second powder or following a second chemical reaction between at least one element of the first powder and at least one metal element of the second powder, a working temperature low enough to prevent the first powder from melting being imposed during the formation of the ceramic material.

摘要： The present invention relates to a method for manufacturing a part made of a ceramic matrix composite material, the method including at least the following step: infiltrating a fibrous preform with a molten composition including mostly silicon by weight, the fibrous preform comprising silicon carbide fibres, a silicon carbide powder being present in the pores of said preform, the mean size of the silicon carbide crystallites in the powder being smaller than the size of the silicon carbide crystallites in the fibres, a ceramic matrix being formed in the pores of the fibrous preform during the infiltration so as to obtain the part made of composite material.

摘要： A die or piston of a spark plasma sintering apparatus, characterised in that said die or said piston is made from graphite and the outer surfaces of said die or of said piston are coated with a silicon carbide layer with a thickness of 1 to 10 micrometres, said silicon carbide layer being further optionally coated with one or more other layers made from a carbide other than silicon carbide chosen from hafnium carbide, tantalum carbide and titanium carbide, the other layer(s) each having a thickness of 1 to 10 micrometres. A spark plasma sintering (SPS) apparatus comprising said die and two of said pistons, defining a sintering, densification or assembly chamber capable of receiving a powder to be sintered, a part to be densified, or parts to be assembled. A method of sintering a powder, densifying a part, or assembling two parts by means of a method of spark plasma sintering (SPS) in an oxidising atmosphere, using said spark plasma sintering (SPS) apparatus.
