Alumina Ceramic Substrate Description
Alumina Ceramic Substrate is a new type of precision thermal conductive ceramic chip, industrial thermal conductive ceramic chip and functional thermal conductive ceramic chip product. Due to the high cost of raw materials and the particularity of forming process, alumina ceramic substrate are mainly used in high-tech fields, such as metallurgy, chemical industry, electronics, national defense, aerospace and nuclear technology.
Alumina Ceramic Substrate Properties
Alumina Ceramic Substrate is a kind of special ceramics, which has high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, insulation and other excellent characteristics, which is concerned by many industries. It has incomparable advantages in integrated circuit chip and aviation optical components.
At present, the market demand for 99 alumina thermal conductive ceramic chips is increasing. While 95 alumina ceramics are highly sought after, it also gives birth to the rapid development of alumina ceramic manufacturers and companies. Alumina ceramic ball and a series of related business companies came into being and developed rapidly.
Ceramic alumina is widely used in the whole ceramic industry, and its performance is also very superior. Its heat conduction, insulation and heat dissipation are the basic characteristics.
Alumina Ceramic Substrate is more and more widely used in its actual life. At the same time, alumina ceramic sheet which can meet various special performance requirements must have the following three characteristics:
1、 The Rockwell hardness of alumina ceramic substrate can reach hra80-90, which is second only to diamond.
2、 The results show that the wear resistance of alumina ceramic is 266 times higher than that of manganese steel and 171.5 times higher than that of high chromium cast iron. According to the customer's follow-up survey in recent ten years, the service life of the equipment can be improved at least ten times under the same conditions.
3、 The density of alumina ceramic substrate is only 3.5g/cm3, which is less than half of that of steel, which effectively reduces the load of equipment. If it is made of alumina ceramic sheet, it is better to operate and lighter. It can also be customized according to the customer's drawing size.
|Greige density g/cm3||2.48|
|Shrinkage rate %||13.39|
|Finished product density g/cm3||3.77|
