High-dielectric-constant ceramic dielectric material and preparation method thereof
The invention discloses a high-dielectric-constant ceramic dielectric material and a preparation method thereof, and belongs to the technical field of ceramic dielectric materials. The material is prepared from the following components in percentage by mass: 80-90 percent of BaO-5.75Fe2O3-0.5NiO and 10-20 percent of BaSiO3 microcrystalline glass. The preparation method comprises the following steps: carrying out ball milling, heating and mixing on raw materials to prepare a blank, gradually heating to 1100-1150 DEG C according to a certain heating rate, carrying out heat preservation for 0.5-2 hours, and cooling to obtain the ceramic dielectric material. The problem that the capacitance temperature coefficient of an existing ceramic dielectric material is large in change amplitude within the range of -55 DEG C to 150 DEG C is solved. The material has the characteristics of high dielectric constant, low dielectric loss and stable temperature coefficient.
