Lasers

Laser outputs have been progressively increasing over the last decade; while thermal management and heat dissipation remain a crucial factor for overall laser performance and lifetime. Beryllium Oxide is the premier choice for application in semiconductor diode laser arrays and gas lasers because it possesses the highest thermal conductivity of all oxide ceramic materials currently known to exist in the universe.

Microwave

High and Low power radar systems require materials exhibiting low dielectric constants and very low dielectric loss factors, otherwise referred to as dissipation factor or tan σ. Beryllium Oxide is most often the material selected for these requirements by virtue of its low dielectric loss. Since BeO is transparent to microwaves, it may be used as windows, radomes, and antennas for microwave communication systems and high power industrial microwave ovens. Furthermore BeO exhibits appropriate mechanical strength and dielectric strength when used in high power, high frequency applications. Learn More »

Electronic

Electrical components requiring high resistivity mounting substrates that exhibit matched expansion coefficients and high voltage breakdown strengths are also perfect candidates for the use of high thermal conductivity Beryllium Oxide. Learn More »

Aerospace

Avionics components benefit from the low specific gravity of Beryllium Oxide. Concomitant with its high specific stiffness, dielectric strength, and superior thermal conductivity, BeO offers unique advantages in many aerospace applications where densely packed components require lightweight electric isolation, specifically for onboard missile systems and countermeasures avionics.

Medical

Heat dissipation is often a prime requirement in the miniature circuitry used in ever shrinking medical devices. BeO has distinguished itself by way of its excellent thermal performance in gas lasers used for DNA and tissue analysis, portable defibrillators, and blood glucose meters for diabetics. Beryllium Oxide is the preferred choice for applications requiring rapid thermal transfer combined with dielectric and mechanical strength. Learn More »

Nuclear

Early research and development work on beryllium oxide was directed toward the nuclear industry. BeO has specific properties such as low neutron capture cross section and high neutron moderating ability which make it an attractive material for nuclear applications. Furthermore its high melting temperature allows it to be used where other refractory materials will not provide the set of properties necessary for these situations. Additionally, BeO is transparent to x-rays and can therefore be employed as an x-ray window, particularly where operating conditions can be severe. Learn More »

Refractory

Applications requiring prolonged exposure to very high temperatures will be adequately served through the use of Beryllium Oxide. With a melting temperature which exceeds Alumina by 400°C, and a safe use temperature in excess of 2000°C, BeO is ideal for thermocouple protection tubes, furnace lining brick, setters, crucibles, and other refractory requirements.

Research & Development

Research and Development on Beryllia continues so material processing improvements can realize even greater thermal transfer in American Beryllia products. Our aim is to have the thermal conductivity of BeO monolithic materials more closely approach theoretical values. Additionally, development of thermally conductive pastes and adhesives continue such that the ever-increasing performance needs of our customers may be achieved. Learn More »

American Beryllia Inc. is recognized throughout the world as a leading manufacturer of Beryllium Oxide (BeO), advanced ceramic components, and compounded materials. 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, commonly called Beryllia, and developed in the 1950s as a space-age technical ceramic material, offers a uniquely desirable combination of properties which are not found in any other ceramic material. Distinguished by its excellent thermal conductivity, 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.

American Beryllia provides both fired ceramic parts under the trade name Berlox^® and unfired BeO powder compounds. Typical applications for BeO ceramic include heat sinks for high power electronics, laser diodes, and advanced avionics. It is also an ideal refractory material which can be used for both nuclear reactors and very high temperature furnace applications.
