摘要

Method of applying a sintered layer containing a metal of high melting point to a ceramic article, particularly to an article consisting of alumina of high purity and high density, applying a mixture of a metal of high melting point finely divided and an additive to the surface of this article and then sintering the applied mass, characterized in that a material consisting mainly of CaO, of a mixture of CaO and Al2O3 and/or SiO2, of a compound of two or more of these oxides containing Ca, a mixture of two or more such compounds or a mixture of one or more such compounds and one or more said oxides, the molar ratio Al 2 O 3 being: CaO less than 2,25 and the molar ratio (Al2O3 + CaO): SiO2 greater than 0.35 in said additive.
