Vacuum electrode introduction
Vacuum ceramic electrode is an important component often used in electronic devices and industrial applications. It is made of high purity ceramic material with excellent insulation properties and high temperature resistance. Vacuum ceramic electrode is widely used in vacuum circuit breaker, vacuum tube, radar system, medical equipment and other fields.
The ceramic vacuum electrode is mainly composed of ceramic material and metal material, wherein the metal material acts as the conductive layer and the ceramic material acts as the insulating layer. The design of this structure makes the ceramic vacuum electrode have the advantages of high conductivity, high temperature resistance and corrosion resistance.
1.Vacuum electrode Structure and process
Vacuum ceramic electrodes are usually composed of two parts: a conductive part and an insulating part. The conductive part is made of metal materials, such as copper, tungsten, etc., to provide good electrical conductivity; The insulation part is made of high purity ceramic materials, such as alumina and zirconia. The process for manufacturing a vacuum ceramic electrode consists of the following steps:
2.Vacuum electrode Material selection
In order to ensure the stability and reliability of the vacuum ceramic electrode, it is necessary to select high purity metal materials and ceramic materials. Metal materials need to have good electrical conductivity and mechanical strength; Ceramic materials need to have excellent insulation properties and high temperature resistance.
3.Metal preparation
The metal material is processed and formed by casting, milling, sintering and other processes, and then the conductive part is treated on the surface to improve its bond strength with the ceramic part.
4.The preparation of insulating parts
mainly includes the forming and sintering of ceramic materials. First, the high-purity ceramic powder is mixed with an organic binder and molded by injection molding or pressing. The molded part is then sintered to form a dense ceramic structure.
