China Ceramics Materials applied for patents for COG type ceramic dielectric materials and their preparation methods and multilayer chip ceramic capacitors, so that the MLCC ceramic layer has good dielectric properties and reliability_Composition_Display

According to financial news on August 4, 2024, Tianyancha intellectual property information showed that Shandong Guoca Functional Materials Co., Ltd. applied for a project called "COG type ceramic dielectric materials and their preparation methods and multilayer chip ceramic capacitors". ", Publication No. CN202410363096.1, application date is March 2024.

The patent abstract shows that the present invention provides a COG type ceramic dielectric material, a preparation method thereof and a multilayer chip ceramic capacitor, and relates to the technical field of ceramic dielectric materials. The COG type ceramic dielectric material is mainly composed of a main component, a modified component and a sintering aid component; the main component is (BaxSr1-x)zZrhO3, where 0.2＜x＜0.5, 0.993, Re2O3, BaCO3 and CaCO3, where Re is selected from From at least one of Y, Ho, Yb, Gd, Dy, Sm, Nd and Er; the sintering component is MnSiO3. The combination of the main components, modified components and sintering aid components in the COG type ceramic dielectric material enables the manufactured MLCC ceramic layer to have good dielectric properties and reliability.
