The invention discloses a ferrotitanium bismuth cobaltate ceramic material with five-laminated structure and multiferroic performance and a preparation method thereof, belong to the technical field of oxide ceramic materials. The chemical formula of the ferrotitanium bismuth cobaltate ceramic material is Bi6FeCoTi3O18. The preparation method comprises the following steps of: selecting analytically pure Bi2O3, analytically pure Fe2O3, analytically pure Co2O3 and spectroscopically pure TiO2 serving as raw materials, wherein the molar ratio of Bi2O3 to Fe2O3 to Co2O3 to TiO2 is (6-6.6):1:1:6; and performing ball milling, drying, pre-synthesis, secondary ball milling, drying, molding, plastic removal and sintering by adopting the conventional solid-phase sintering process to obtain Bi6FeCoTi3O18. Conventional raw materials and the current solid-phase process are adopted, and the preparation steps are performed at the low-pressure condition, so that the obtained product has high ferroelectricity and high ferromagnetism. The ferrotitanium bismuth cobaltate ceramic material has the advantages of simple process, high stability, low sintering temperature, material nontoxicity and high environmental coordination.
