A zirconium oxide ceramic ferrule workblank production process includes the steps of: with unique raw material formula, performing mixing and granulation; performing low-speed injection moulding at 165-180 DEG C and under the pressure of 0.8-1.2 MPa; and performing defatting in a six-section temperature-control manner and sintering in the six-section temperature-control manner to form the zirconium oxide ceramic ferrule workblank. The process method is stable and solves the problem that a method in the prior art is low in productivity, is high in cost, is complex to control, is low in finished product yield of the workblank, and is poor in performances, such as hardness, compactness and the like, of the workblank.
