Analysis of insulating ceramic materials

Analysis of insulating ceramic materials

Insulating ceramic materials are favored by many people because of their beauty, cleanliness and practicality. With the rapid development of modern society, many people are paying attention to this product. The following is an analysis of insulating ceramic materials by Pintejin ceramic manufacturers. Alumina insulating ceramic tube Insulating ceramics, also known as device ceramics, are used in electronic equipment to install, fix and protect components, as an insulating support for current-carrying conductors and ceramics for various integrated circuit substrates.

It has low dielectric constant, low dielectric loss, high mechanical strength, and high dielectric strength, insulation resistance and thermal conductivity. Commonly used insulating ceramics include alumina ceramics, talc ceramics, etc. With the development of the electronics industry, especially The advent of thick film, thin film circuits and microwave integrated circuits has put forward higher requirements for packaging ceramics and substrates. There are many new varieties, such as alumina ceramics, beryllium oxide ceramics, and boron nitride ceramics. At present, the research and development of aluminum nitride ceramics and silicon carbide ceramics are underway, and their common feature is high thermal conductivity.

Alumina insulating ceramic shaft The deformation of insulating ceramic materials in life generally has the following conditions, elastic deformation, statue deformation and fracture. These different deformation causes are different and have different effects. The following describes these deformation conditions for you.

  • 1. Elastic deformation of insulating ceramic materials The elastic deformation of ceramic materials mainly refers to the fact that the material has no obvious shape change under the action of static tension, but some deformation occurs inside the material, which is mainly manifested as internal deformation of the material. It is different from metal materials, usually we cannot see it with the naked eye.
  • 2. Plastic deformation of insulating ceramics Plastic deformation of ceramic materials is usually deformation at high temperature and fracture during movement. Due to the increase in temperature, the ceramic material has the ability to plastically deform, coupled with changes in the internal structure of the material, plastic deformation occurs.
  • 3. Fracture of insulating ceramic materials The fracture of insulating ceramic materials is usually caused by the deformation of strong tension.

Because the ceramic material itself is relatively brittle and has low tensile strength, it is easy to break under the action of external force. In order to reduce the deformation of insulating ceramic materials, its hardness and tensile strength should be strengthened. When firing ceramic materials, techniques should be optimized to achieve a higher hardness of the ceramic material so that we can use the material more widely. Above is the deformation of the insulating ceramic material.
