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.

Ceramics constant k.

Ceramic composition and properties atomic and molecular nature of ceramic materials and their resulting characteristics and performance in industrial applications. We have collected a number of charts detailing applications and properties for some of the most commonly used ceramic materials. 5 varies somewhat by exact resin content. 6 cheap shielded cables are often made with this stuff but these are only suitable for audio frequencies or low rate data communications.

Beryllium oxide is widely used in aerospace nuclear power metallurgical engineering electronics industry rocket manufacturing and so on. 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. 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. Industrial ceramics are commonly understood to be all industrially used materials that are inorganic nonmetallic solids.

The range of ks for common ceramic dielectrics is shown in table 15. The more resin the lower the k. Measurements are generally carried out at 1 khz.
