Abstract

The invention provides activated molybdenum-manganese slurry used in ceramic metallization and a preparing method thereof. The slurry comprises, by mass percentage, 0.5% of added herring oil, and 0.1% of soybean lecithin, so that degree of finish of a prepared ceramic metallization printed layer can be raised from 85% to 95% or above, and the sealing strength of the metallization is raised from a range (larger than or equal to 70 MPa) to a range (larger than or equal to 100 MPa). The provided preparing method is simple in technology and easy to operate; meanwhile, the complexity of the preparing procedures is reduced, the preparing method has good repeatability, and thus the preparing method is suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of electronic materials, and in particular relates to an activated molybdenum-manganese slurry for ceramic metallization and a preparation method thereof. Background technique [0002] Due to the performance characteristics of ceramics such as high strength, small dielectric constant, high volume resistivity, small dielectric loss and high thermal shock resistance, ceramic parts themselves are excellent insulating materials, and they do not have solderability themselves. Solder usually cannot Its infiltration and metallization are an effective way to realize the sealing of ceramics and metals. [0003] The raw materials and formulations used in ceramic metallization are the key to metallization. In actual production, different manufacturers have different special raw material formulas. The paste or slurry composed of specific formula raw materials can effectively achieve the coating of specific parts of ce...
