Paste formula for improving binding force between metallization and ceramic
The invention discloses a paste formula for improving binding force between metallization and ceramic, and belongs to the technical field of ceramic metallization. The ceramic metallization paste comprises the following raw materials in percentage by mass: 12.5%-15.5% of manganese powder, 5.4%-8.2% of low-temperature molten oxide, 0.4%-0.7% of strontium sulfate, 14.0%-16.8% of a binder and the balance of molybdenum powder. The low-temperature molten oxide comprises the following components in percentage by mass: 84%-89% of aluminum oxide, 10.5%-15% of silicon dioxide, 0.3%-0.6% of calcium oxide and 0.1%-0.4% of montmorillonite. The traditional ceramic metallization molybdenum-manganese paste formula is optimized, the novel molybdenum-manganese paste is prepared by increasing the manganese content, reducing the low-temperature molten oxide content and then adding strontium sulfate microspheres, the novel molybdenum-manganese paste is applied to welding of 95% aluminum oxide ceramic and metal, the welding performance is remarkably improved, the thickness of the obtained metallization coating is 8-40 microns, the thickness of the nickel layer is 1-5 microns, and the metallization tensile strength is not lower than 175 MPa, and the application range is wide.
