The invention provides a ceramic sintering additive and a production method thereof. The ceramic sintering additive is composed of a multi-metal oxygen cluster and water soluble cationic polyelectrolyte, wherein the multi-metal oxygen cluster is composed of multiple metals, and multiple functional ingredients can be introduced by utilizing the multi-metal oxygen cluster as the sintering additive, and thus the multifunctionality and the excellent mechanical performance are given to a ceramic sintering body; the multi-metal oxygen cluster is an inorganic cathonic cluster of an uncertain structure in essence, and the cathonic polyelectrolyte is polyelectrolyte with positive charge on a polymer chain in essence, so that compounding of the cathonic polyelectrode and the multi-metal oxygen cluster is simple and feasible mixing of ions with opposite charges, universality is realized, stability of the multi-metal oxygen cluster is improved by virtue of the solubility property of the polyelectrode, and multiple functional factors supported by the multi-metal oxygen cluster can be dispersed in ceramic raw material powder relatively uniformly, so that functionality of a ceramic material is improved.
