Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics.
Ceramics constant k.
The dielectric constant k and loss factor tan d can be measured using a standard impedance bridge or an impedance analyzer both of which provide a direct reading.
The loss factor represents the ratio of resistance to reactance of a parallel equivalent circuit of the ceramic element figure 3.
5 varies somewhat by exact resin content.
Beryllium oxide is widely used in aerospace nuclear power metallurgical engineering electronics industry rocket manufacturing and so on.
At present the thermal conductivity of the prepared beo ceramics can reach 280 w m k which is 10 times higher than that of aluminum oxide al2o3 ceramics.
Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications.
The range of ks for common ceramic dielectrics is shown in table 15.
While the data in these charts is in most cases typical of what you will find from ceramic component suppliers it is only intended to be a general point of reference and should not be used for material selection or specification.
Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids.
The more resin the lower the k.
We have collected a number of charts detailing applications and properties for some of the most commonly used ceramic materials.
