Beschreibung
Zusammenfassung:	The invention discloses GNPs/YSZ composite ceramic powder as well as a preparation method and application thereof, and belongs to the technical field of ceramic materials, and the specific scheme is as follows: the GNPs/YSZ composite ceramic powder comprises GNPs powder and YSZ powder coated with silica sol. The preparation method comprises the following steps: 1, uniformly mixing nano-scale GNPs powder, a dispersing agent, silica sol and deionized water, then adding a binder, uniformly mixing to obtain a mixed solution A, and carrying out spray granulation to obtain silica sol coated GNPs powder; and 2, uniformly mixing the GNPs powder coated with the silica sol with YSZ powder, and sintering to obtain the GNPs/YSZ composite ceramic powder. And the GNPs/YSZ composite ceramic powder is deposited on the kovar alloy, and the GNPs/YSZ composite ceramic coating without the bonding layer is formed on the kovar alloy. The preparation process is simple, the cost is low, and mass production can be realized. 一种GNPs/YS
