Black zirconia ceramic material and preparation method thereof

The invention belongs to the field of zirconia ceramic injection molding, and particularly relates to a black zirconia ceramic material and a preparation method thereof. The black zirconia ceramic material is prepared by injection molding of zirconia ceramic feed and infiltration of black pigment suspension. The zirconia ceramic feed comprises zirconia powder, a pore-forming agent and a binder, wherein the mass ratio of the zirconia powder to the pore-forming agent to the binder is (75-85): (3-5): (12-20). The black zirconia ceramic material disclosed by the invention is uniform in color and has good physical properties. The invention further provides a preparation method of the black zirconia ceramic material, the black zirconia ceramic material is prepared through injection molding of the zirconia ceramic feed and infiltration of the black pigment suspension, the process is simple, the cost is low, the operation is convenient, and the industrialization is easy. 本发明属于氧化锆陶瓷注射成型领域，具体涉及一种黑色氧化锆陶瓷材料及其制备方法。所述的黑色氧化
