METALLIZATION AND/OR BRAZING METHOD, USING A SILICON ALLOY, FOR OXIDE CERAMIC PARTS WHICH ARE NON-WETTABLE BY SAID ALLOY

摘要

The invention relates to a metallization method using a silicon alloy that melts at a temperature T1. According to the invention, the aforementioned alloy is used to metallize certain areas of the surface of an oxide ceramic part that is non-wettable by said alloy. The inventive method comprises the following successive steps: carbon is deposited on the areas of the part to be metallized; silicon alloy in solid form is deposited on at least one section of said part, such that there is at least one point of contact between the alloy and the areas to be metallized; and, subsequently, the part and the composition are heated together to a temperature greater than or equal to T1, the molten alloy collecting on the areas to be metallized. The aforementioned method can also be used for the brazing of parts which include at least one oxide ceramic part that is non-wettable by said composition. The inventive methods can be used in the field of electronics, electrical engineering, thermal engineering and chemical engineering.
