The invention provides a preparation method for a zirconia ceramic ferrule and a preparation method for zirconia powder base material used for the zirconia ceramic ferrule. According to the preparation method for the zirconia ceramic ferrule and the preparation method for zirconia powder base material used for the zirconia ceramic ferrule, the adopted titanium dioxide makes the materials have an excellent mobility in the injection molding process, magnesium oxide, zinc oxide and titanium oxide effect synergistically, a coefficient of linear expansion and a thermal stress performance better than that of pure zirconia ceramic is obtained, at the same time, the thermal mechanical performance of the whole system is improved, and high strength of the material is achieved. Secondly, ethylene-vinyl acetate copolymer possesses higher elasticity and tenacity, and polyurethane elastomer, aldehyde resin, high-melting strength polypropylene and the like are interpenetrated in zirconia powders to polymerize through the ethylene-vinyl acetate copolymer, so that the organic bond can form a structure interpenetrating the network well, a stable structural system is obtained, and the formed ceramic ferrule is not prone to deform. Thirdly, the aldehyde resin is an organic binding agent, so that the strength of a molded green is high, the conformality is good, degreasing speed is high, and the precision is high.
