5G ceramic filter material and low-temperature sintering method and application thereof

The invention relates to a filter material, in particular to a 5G ceramic filter material and a low-temperature sintering method and application thereof, and belongs to the technical field of ceramic materials. The invention discloses a low-temperature sintering method of a 5G ceramic filter material. The method comprises the following steps: S1, proportioning raw materials according to a stoichiometric ratio of a ceramic material; s2, the raw materials are mixed and then subjected to high-energy ball milling treatment, and ceramic powder is obtained; the high-energy ball milling is a dry milling process adopting a tungsten carbide milling tank and a milling ball, the milling ball is one or a combination of two of a milling ball with the diameter of 4-6mm and a milling ball with the diameter of 8-10mm, and the weight ratio of the ball to the material is (20: 1)-(80: 1); and S3, carrying out dry pressing on the ceramic powder obtained in the step S2 to prepare a wafer, sintering at 1000-1300 DEG C, and carryin
