Advantages Of Beryllium Oxide Ceramic Substrate
Beryllium oxide ceramic substrate has the characteristics of high thermal conductivity, high melting, strength, high insulation, low dielectric constant, low dielectric loss and good packaging process adaptability. It is used in microwave technology, electric vacuum technology, nuclear technology, micro The field of electronics and optoelectronic technology is widely used.
Beryllium Oxide Ceramic Substrate Applications
Beryllium oxide ceramics have been widely used because of their electromechanical and thermal properties unmatched by other ceramics. Especially in high-power semiconductor devices, high-power integrated circuits, high-power microwave vacuum devices and nuclear reactors, it has always been the mainstream ceramic material for the preparation of high thermal conductivity components, and it plays a very important role in the military field and the national economy.
BeO ceramic products are also a refractory material. BeO ceramic crucibles can be used to melt rare metals and precious metals, especially where high-purity metals or alloys are required. The working temperature of the crucible can reach 2000°C. Due to its high melting temperature (approximately 2550°C), high chemical stability (alkali resistance), thermal stability and purity, BeO ceramics can also be used to melt uranium and plutonium. In addition, these crucibles have also been successfully used to make standard samples of silver, gold and platinum. BeO’s high degree of “transparency” to electromagnetic radiation allows the use of induction heating to smelt the metal samples in it.
In avionics technology conversion circuits and aircraft and satellite communication systems, BeO is widely used as bracket components and assembly parts; it also has application prospects in spacecraft electronics. The use of BeO ceramics has particularly high thermal shock resistance and can be used in the squib of jet aircraft. Metal-coated BeO sheets have been used in the control system of aircraft driving devices; Ford and General Motors have used metal-sprayed beryllium oxide linings in automobile ignition devices. BeO ceramics have good thermal conductivity and are easy to be miniaturized. They have broad application prospects in the laser field. For example, BeO lasers have higher efficiency and higher output power than quartz lasers.
Beryllium Oxide Ceramic Basic Information
The melting temperature of beryllium oxide ranges from 2530°C to 2570°C, and its theoretical density is 3.02g/cm³.
It can be used for a long time at 1800°C in a vacuum, and can be used at 2000°C in an inert gas, and only volatilizes at 1800°C in an oxidizing atmosphere.
The most outstanding performance of beryllium oxide ceramics is its large thermal conductivity (the thermal conductivity λ is 200-250W/(mK)), which is similar to metal aluminum and 6-10 times that of aluminum oxide. Therefore, BeO ceramics is a unique electrical and thermal And mechanical properties of precision ceramic materials.
