Abstract
PURPOSE: To form a metallized layer which has a high bonding strength between attached material and surface of sapphire.
CONSTITUTION: A metalized layer in which some glass components are added into a powder of Mo or W, is baked on a surface of sapphire 1. With this glass component, wetting property to the surface of sapphire is improved and a strong bonding is obtained, and also the powder is well combined. The glass component is, on consideration of atmosphere of the metalizing treatment, the termal expansion coefficient and the bonding strength, alumina as the main component and silica is added with mol ratio 1:8 and is mixed. By forming an Ni plated layer 3 on the metalized layer, immersion of solder into the layer 2 is prevented when the brazing is made. Then, an attached metal 5 is bonded with solder 4. An alloy having a thermal expansion coefficient close to that of sapphire is used for the metal 5, and the soldering is made using an Ag solder etc. having lower melting point than that of the layer 2. With this method, it is able to bond strongly an attached metal on sapphire.
