Description

technical field [0001] The invention relates to a ceramic material and a preparation method thereof. Background technique [0002] Ceramic materials are a kind of inorganic non-metallic materials made of natural or synthetic compounds through molding or high-temperature calcination. There are many types of ceramics and different uses. Most of the shells of capacitors are made of ceramics, so there are certain requirements for the dielectric constant, compressive strength, and melting point of the material. In the prior art, a single raw material is used to make ceramic materials, which limits the use of such materials. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a ceramic material and a preparation method thereof. [0004] In order to solve the existing problems, the technical solution adopted by the present invention is: a ceramic material, comprising the following components in parts by weight: 10-30 parts of p...
