Beryllia Heat Sinks, BeO

Product Information

It 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 temperature high performance refractory components for nuclear reactors. 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 aluminum oxide or aluminum nitride and, in addition, offers thermal conductivity ten times higher than alumina, and fifty percent higher than aluminum nitride, a dielectric constant that is lower than both alumina and aluminum nitride, and weight per given volume that is fully a quarter less than alumina, and nearly ten percent less than aluminum nitride. As a thermally conductive and electrically insulating material its performance is exceeded only by that of diamond. it is an ideal material for applications requiring large heat dissipation as well as dielectric and mechanical strength. It is particularly well suited for use as a diode laser and semiconductor heat sinks and as a rapid thermal transfer medium for miniaturized circuitry and tightly contained electronic assemblages.

These products range from heat sinks, crucibles, rods, washers, and thermocouple tubing to large monolithic radar and nuclear, and custom-made substrate components for a diverse range of aerospace, defense, electronic, and commercial applications. Beryllium oxide ceramic heat sinks are made of high purity beryllium oxide ceramics.

Packing of Beryllia Heat Sinks

Standard Packing:

Sealed bags in carton boxes. Special package is available on request.

As a ceramic material, BeO is quite fragile in a lot of cases. The Beryllia Heat Sinks are usually held in plastic bags by vacuum, and protected with heavy foam.

ATTs’ Beryllia Heat Sinks is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
