The heat dissipation principle of alumina ceramic sheets
Time: 2021-11-05   Writer: Mingrui Ceramics
The excellent performance of alumina ceramics has made it widely used in various fields. Below, Mingrui Ceramics will introduce the heat dissipation principle of alumina ceramics.
Alumina ceramic sheets
Alumina ceramic sheets are special ceramics with high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, insulation and other excellent characteristics. They have attracted the attention of many industries. They have other thermal conductivity in integrated circuit chips and aviation optical components. Unmatched advantages of insulating materials.
Nowadays, there is an increasing demand for alumina ceramic heat sinks in the market. While the heat dissipation principle of radiators is highly sought after, it has also given birth to the rapid development of heat sink principle companies. A series of related companies, such as the principle of heat sinks, emerged at the historic moment and developed rapidly.
Alumina ceramic chip products are a new type of precision ceramic parts, electronic and electrical ceramics, military ceramics, and functional ceramics that are currently widely used. Due to the expensive raw materials of alumina ceramic chips and the particularity of the forming process, alumina ceramic chips are currently mainly used in high technology, such as metallurgy, chemical industry, electronics, national defense, aerospace and nuclear technology and other high-tech fields.
Alumina ceramics are widely used in the entire ceramic industry and are also very superior in performance. Its thermal conductivity, insulation, and heat dissipation are the basic characteristics, and ceramic alumina ceramic sheets are more and more widely used in their actual life. At the same time, ceramic alumina sheets that can meet various special performance requirements need to have the following three characteristic:
1. High hardness of alumina ceramic sheets
The Rockwell hardness of the alumina ceramic chip tested by a third-party professional organization can reach HRA80-90, which is second only to diamond.
2, the wear resistance of the alumina ceramic sheet is good
The overall wear resistance of alumina ceramic sheets has exceeded manganese steel by more than 266 times and high chromium cast iron by more than 171.5 times. According to customer surveys in the past ten years, if it is under the same conditions, the service life of the equipment can be increased by at least ten times.
3. Light weight of alumina ceramic sheets
The density of alumina ceramic chips is only 3.5g/cm3, which is less than half of that of steel, which effectively reduces the load on the equipment. If it is made of alumina ceramic sheet, it is better to handle and lighter.
