The invention relates to a bismuth borosilicate glass coated fine grain barium titanate ceramic dielectric material and a preparation method thereof. The preparation method comprises the following steps: preparing bismuth borosilicate glass sol by using a sol-gel method, wherein bismuth borosilicate glass is Bi2O3-B2O3-SiO2 glass; the preparation method comprises the following steps: dispersing BaTiO3 powder into bismuth borosilicate glass sol to obtain BaTiO3 powder coated with the bismuth borosilicate glass sol; and calcining the bismuth borosilicate glass sol coated BaTiO3 powder to obtain the bismuth borosilicate glass coated fine grain barium titanate ceramic powder. Granulating and forming the bismuth borosilicate glass coated fine-grain barium titanate ceramic powder to obtain a barium titanate ceramic green body, and heating to obtain fine-grain barium titanate dielectric ceramic, namely the bismuth borosilicate glass coated fine-grain barium titanate ceramic dielectric material. Compared with the prior art, the glass-coated BaTiO3 powder is prepared by a sol-gel method to form the core-shell structure powder, and the core-shell structure powder of the glass-coated BaTiO3 powder is used for preparing fine grain barium titanate ceramic and can be widely applied to the field of application of electronic materials.
