Feed for aluminum oxide injection molding, aluminum oxide ceramic and preparation method

The invention relates to the technical field of ceramic powder injection molding, and particularly discloses a feed for aluminum oxide injection molding, aluminum oxide ceramic and a preparation method.The feed for aluminum oxide injection molding is prepared from 83-86 parts of aluminum oxide ceramic powder and 14-17 parts of organic matter, the organic matter is prepared from 16 to 27 weight percent of polypropylene, 12 to 21 weight percent of polyethylene, 8 to 16 weight percent of PE compatilizer, 13 to 35 weight percent of paraffin and 10.5 to 28 weight percent of additive. The invention aims to provide the feed for aluminum oxide injection molding, so that a ceramic green body prepared by adopting the feed does not deform during glue discharging, is high in density and is easy to mold and demould; further, the aluminum oxide ceramic with high density, small shrinkage and high precision is provided; the invention further provides a preparation method of the aluminum oxide ceramic, the problems of toxicit
