Beryllium Oxide Ceramic Insulators

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.

Beryllium oxide ceramic insulators.

Beryllium oxide has a density fully 25 lower than alumina. 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. As an amorphous solid beryllium oxide is white its high melting point leads to its use as a refractory material. 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.

For applications involving high frequency or high pulse rate circuitry the inherent low electrical capacitance of these. Although beryllium oxide is toxic beryllium oxide ceramics are not toxic. Beryllium oxide beo also known as beryllia is an inorganic compound with the formula beo. 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.
