Method principle

Sintered refractory metal sintered refraetary metal}} rc} cess is commonly known as multilayer sealing. It is a common ceramic-metal sealing method. Its Renyi process applies 1-J layer metal powder paste (such as aluminum, aluminum iron, aluminum manganese, or molybdenum plus oxide, etc.) on the ceramic surface (the site to be sealed). ) After sintering in an oxygen furnace, the surface of the ceramic body is metallized, and a layer of nickel is electroplated on the soil, which is called secondary metallization. Finally, silver or silver-copper solder is assembled together with metal parts and metallized ceramic parts and brazed in a hydrogen furnace to obtain ceramic and metal sealing parts. This method has high sealing strength, good air tightness, and can be continuously mass-produced. ^[1]
