Problems solved by technology

[0002] Electronic ceramic dielectric materials are mainly used to make ceramic capacitors, among which high-voltage ceramic materials are mainly used to make medium and high-voltage ceramic capacitors, ultra-high-voltage ceramic capacitors, etc., which are a type of ceramic material with large consumption and high importance, and have high performance requirements. Some manufacturers produce this ceramic material, but there are disadvantages such as low withstand voltage, large loss, and unstable performance, so it cannot be used in some occasions that require stricter performance requirements for ceramic dielectric materials.
