The invention relates to the use of ternary alloys in brazing ceramics. Brazing is a process of limited usefulness in the fabrication of ceramic components because of the inability of many alloys to wet industrially important ceramics. A possible solution is the metallizing of ceramics but this has technical and economic disadvantages. Alloys are known which wet ceramics but they do not necessarily give good bond strength. The following alloys have now been devised which both wet ceramics and give good bond strength, e.g., greater than 40 MNm.sup.-2 at room temperature, with unmetallized ceramics. The alloys are:
