Home Products Technical Ceramics Beryllium Oxide Ceramics BW Advanced Ceramics THERMALLY SUPERIOR BERYLLIUM OXIDE – BW CERAMICS FAMILY OF PRODUCTS Materion offers a family of beryllium oxide (BeO or beryilla) ceramics that meet the demanding requirements of smaller components exposed to high ambient temperatures, but difficult to air or liquid cool. Our BW beryllia engineered ceramics are our highest quality advanced BeO ceramics that address all the needs for reliable thermal conductivity. ADVANTAGES OF BW 1000® AND BW3250® TECHNICAL CERAMICS BeO ceramic can be nine times more thermally conductive than AlN ceramic. When BeO is compared to AlN, it has a thermal conductivity of up to 325 W/(m•K), meaning beryllia can be up to 80 percent more thermally conductive than AlN. In addition, BeO as an oxide ceramic is more chemically stable than AlN ceramics in environments containing oxidizing chemicals. Our beryllium oxide advanced ceramics are available in four grades, two of which are: BW 1000 and BW3250. Both are 99.5% pure BeO and deliver improved performance for circuits and applications generating high heat. BeO has a lower dielectric constant of 6.7 compared to AlN's 9.7 dielectric constant. BW ceramics offer electrical resistivity and dielectric strength equivalent to competitive materials. BW 1000 offers the highest flexural strength (MOR) of all our beryilla ceramic grades. When small components require great strength, BW 1000 is the optimum choice. This ceramic material is ideal for very small, fragile parts that will endure high levels of stress during the life cycle of the product. BW3250 BeO ceramic offers higher thermal conductivity than BW 1000, but with lower flexural strength. Learn more about the technical properties of our BW family of ceramics from our data sheet. USES AND APPLICATIONS OF BW BEO ADVANCED CERAMICS To meet the requirements of a range of applications, the BW family of high-performance BeO ceramic parts are manufactured with various techniques including dry pressing, hot pressing, isostatic pressing and extrusion. BW 1000 ceramics offer the highest tensile strength of all of our beryllium oxide ceramics. This characteristic allows this ceramic to be made into small components in high heat applications including components for medical equipment, military applications, electronic components and traveling wave tubes (TWT). BW3250 is a highest thermally conductive BeO ceramic. We are the only company in the world that offers this higher thermally conductive version. BW3250 is guaranteed up to 325W/mK, but it is capable of running around 350 W/mK. The many uses of BW3250 include: Diode lasers Medical scanning equipment Semiconductor substrates Automotive ignition systems Thick film circuits Components for missile guidance Radio frequency transmitters For additional information on how our BW beryllium oxide engineered ceramics can provide increased thermal management for your next application, talk with our ceramics experts.
