What Is Ceramic Heat Sink?

Components of modern technology products, such as computer chips or light-emitting diodes, generate more and more waste heat during operation, and generally existing heat dissipation devices used to assist heat dissipation components usually include at least a metal heat sink and a fan conducts the waste heat from the operation of the heating element through the heat sink to remove it by air convection, and uses the fan to forcibly accelerate the convection of the air around the heating element to achieve the effect of rapid heat removal. However, the heat transfer coefficient of existing metal heat sinks is not very good. Therefore, heat sinks made of ceramic materials with better heat transfer characteristics appear on the market in order to achieve better heat dissipation effects. Ceramic heat sink classification There are aluminum oxide heat sinks, aluminum nitride heat sinks, and silicon carbide heat sinks . There is the performance comparison between the usual heatsink VS ceramic

Beryllium Oxide Ceramics

Beryllium Oxide (BeO) , which is commonly referred to as Beryllia, is endowed with a virtuously unique combination of thermal, electrical, optical, and mechanical properties which may be exploited for a diverse range of applications from thermal management systems for integrated electronics to high-performance refractory components for nuclear reactors. Applications of Beryllium Oxide Ceramics No other oxide ceramic material collectively exhibits these highly desirable properties and characteristics. BeO ceramic conducts heat more quickly than virtually all metals with the exception of copper and silver. Beryllia exhibits extremely low dielectric loss characteristics, possesses high electrical resistivity, and offers excellent strength with high specific stiffness properties. BeO provides all the desirable physical and dielectric characteristics exhibited by an aluminum oxide or aluminum nitride, in addition, offers thermal conductivity ten times higher than alumina, and fifty percent
