Thermal Conductivity Of Beryllium Oxide Ceramic

Beo ceramic is utilized for its proven superior properties and its cost effectiveness unmatched by aluminum nitride aluminum oxide boron nitride silicon carbide or any ceramic.

Thermal conductivity of beryllium oxide ceramic.

This colourless solid is a notable electrical insulator with a higher thermal conductivity than any other non metal except diamond and exceeds that of most metals. The thermal conductivity of beo is extremely high in comparison with other ceramics particularly below 300 c. With use of beo ceramic in electronic technology one of the main parameters is its high thermal conductivity. Prospects are discussed for the use of beo ceramic in electronic and other fields of technology and special instrument building.

It is ideal for very small fragile parts that will endure high levels of stress during the life cycle of the product. Although beryllium oxide is toxic beryllium oxide ceramics are not toxic. A 20 lower dielectric constant than alumina and aluminum nitride offers advantages in the high frequency field. 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.

As an amorphous solid beryllium oxide is white its high melting point leads to its use as a refractory material. Beryllium oxide beo also known as beryllia is an inorganic compound with the formula beo. 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 versus aluminum nitride.

Beryllium oxide is widely used in aerospace nuclear power metallurgical engineering electronics industry rocket manufacturing and so on. When small components require great strength bw 1000 ceramic is the optimum choice. Bw3250 beo ceramic offers higher thermal conductivity than bw 1000 ceramic but with lower flexural strength. Analysis of publications shows that beo ceramic in the range 300 500 k exhibits the highest thermal conductivity among all ceramic materials used in.

Beryllium oxide is widely used in industry due to its low density and high thermal and electrical conductivity.
