Ceramics Constant K

Beryllium oxide is widely used in aerospace nuclear power metallurgical engineering electronics industry rocket manufacturing and so on.

Ceramics constant k.

Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids. Usually they are metal oxides that is compounds of metallic elements and oxygen but many ceramics. The loss factor represents the ratio of resistance to reactance of a parallel equivalent circuit of the ceramic element figure 3. 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. 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. 6 cheap shielded cables are often made with this stuff but these are only suitable for audio frequencies or low rate data communications. The more resin the lower the k.

Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. The relative dielectric constant k is the ratio of the amount of charge that an element constructed from the ceramic material can store relative to the absolute dielectric constant 0 the charge that can be stored by the same electrodes when separated by a vacuum at equal voltage 0 8 85 x 10 12 farad meter. Measurements are generally carried out at 1 khz.
