| titleOfInvention | A method for high temperature co-firing composite substrate of metal and silicon nitride ceramics |
| abstract | The invention discloses a method for a high-temperature co-firing composite substrate of metal and silicon nitride ceramics, comprising multi-layer ceramics, a silicon nitride ceramic green body film and tungsten-molybdenum slurry. Screen printing process, lamination process, slicing process and production process, devices include: debinding furnace and atmospheric pressure sintering furnace, silicon nitride ceramic green film production process includes: silicon nitride ceramic powder, sintering aid yttrium oxide, Binder, leveling agent and plasticizer, the weight ratio is that yttrium oxide accounts for 4% to 7% of the total weight, the binder accounts for 4% to 8% of the total weight, and the plasticizer and the leveling agent account for the total weight 5% to 8% of the silicon nitride ceramic powder, and the rest is silicon nitride ceramic powder. The above materials are mixed to form a green embryo film and put into a nitrogen atmosphere to remove the glue to obtain a silicon nitride ceramic green green film; a metal and nitride film of the present invention The method of high temperature co-firing composite substrate of silicon ceramics has the advantages of high temperature co-firing metal and silicon nitride ceramics with high thermal conductivity and good flexural strength. |
