Beryllium Oxide Ceramic Insulators

Beryllium oxide is widely used in the fields of special metallurgy vacuum electronic technology nuclear technology microelectronics and photoelectron technology due to its high thermal conductivity high insulation low dielectric constant low medium loss and good.

Beryllium oxide ceramic insulators.

Beryllium oxide versus aluminum nitride when thermal conductivity and heat dissipation are critically important considerations the differences between beryllium oxide beo also known as beryllia and aluminum nitride aln can mean the difference between long term performance and early failure. Beryllium oxide beo also known as beryllia is an inorganic compound with the formula beo. For applications involving high frequency or high pulse rate circuitry the inherent low electrical capacitance of these. Aavid thermal division of boyd corporation.

Comparing theoretical density values beo is 3 01g cc while al 2 o 3 is 4 00 g cc and aln is 3 26 g cc. The coefficient of thermal expansion for beo is comparable to many other oxide ceramics and many metals as well at approximately 7 5 in in c for the range from 25 c. As an amorphous solid beryllium oxide is white its high melting point leads to its use as a refractory material. Beryllium oxide is used in high technology ceramics electronic heat sinks electrical insulators microwave oven components gyroscopes military vehicle armor rocket nozzles crucibles thermocouple tubing laser structural components substrates for high density electrical circuits automotive ignition systems and radar electronic.

Beryllium oxide insulators have a high dielectric strength which allows safe operating voltages of 1500 volts or more.
