Abstract
An assembly (28) of ceramic surfaces (21, 23), particularly refractory metal oxides and carbides, abutting a thin sheet (22) of metal susceptor material are placed in a chamber (10) of an enclosure (14) containing inert gas (36). An r.f. coil (24) is activated by power supply (26) to melt the susceptor (22) and adjacent zones (40, 42) of the ceramic. Reactive gas such as oxygen or a carbonizing gas (38) is then fed to the chamber (10) and reacts with the susceptor (22) to form compounds (47) which disperse and dissolve in the zones (40, 42). On cooling, a strong joint is formed. The susceptor may contain inner perforations (58) and outer perforations (56) to aid in distribution of heat.
