Aluminum oxide ceramic and preparation method thereof
Provided is aluminum oxide ceramic. The aluminum oxide ceramic is prepared from, by weight, 960-1000 parts of aluminum oxide fine powder, 20-40 parts of aluminum oxide nanometer powder, 8-15 parts of water reducing agent, 25-35 parts of dextrin, 110-130 of maltose, 20-40 parts of oleic acid, 25-40 parts of carboxymethyl cellulose and 15-25 parts of hydroxy propyl cellulose. According to the aluminum oxide ceramic, by means of a scientific and reasonable formula and a three-stage sinering technology, the sinering temperature is decreased, the sintering strength and the density of a prepared product are improved, the surface of the product is smooth and free of bubbles, the energy consumption is reduced, and meanwhile the product quality is improved; a prioritization scheme is provided for 3D printing materials for a soft loading creep furnace support rod and the like.
