Abstract:
A process for producing a ceramic member for bonding, said ceramic member comprising:a ceramic base which is a sintered ceramic; a metallic layer formed by metallization, which is a lower layer comprising a nickel ingredient, a tungsten ingredient and a molybdenum ingredient provided on a surface of the ceramic base; and an alloy layer, which is an upper layer comprising a nickel ingredient and at least one of a copper ingredient and a manganese ingredient provided on a surface of the metallic layer directly or through an interlayer, which method comprises: a first step of preparing a lower layer paste with the use of a first mixture comprising a nickel ingredient, a tungsten ingredient and a molybdenum ingredient, applying the lower layer paste to a surface of a ceramic base which is a sintered ceramic, and drying the resultant coating layer to form a lower layer after the applying; a second step of preparing an upper layer paste with the use of a second mixture comprising one of a nickel ingredient and a nickel oxide ingredient and at least one of a copper ingredient, a copper oxide ingredient, a manganese ingredient and a manganese oxide ingredient, applying the upper layer paste to the lower layer, and drying the resultant coating layer to form an upper layer after the applying; and a third step of heating the lower layer and the upper layer to bake the lower layer and the upper layer.
