Capacitor dielectric and piezoelectric ceramics, advanced industrial materials that, by virtue of their poor electrical conductivity, are useful in the production of electrical storage or generating devices piezoelectrics are materials that generate a voltage when they are subjected to mechanical . Porous ceramic products cover wide range of advanced ceramic materials, which can be oxides ceramics: alumina, zirconia, or non-oxides ceramics:carbides, borides, nitrides, silicides the properties of porous ceramic product depend on three main factors: the properties of the ceramic material of which the product is made the topology . Specific high dielectric constant components are produced to customer specification electrically insulating, low loss supports for the dielectrics are also produced these may be required to minimize perturbation of the electromagnetic field in the vicinity of the dielectric.

The term high-κ dielectric refers to a material with a high dielectric constant κ (as compared to silicon dioxide)high-κ dielectrics are used in semiconductor manufacturing processes where they are usually used to replace a silicon dioxide gate dielectric or another dielectric layer of a device. Capacitance of a capacitor is directly proportional to the dielectric constant of the dielectric material used in the capacitor dielectric ceramics are used for manufacturing capacitors, insulators and resistors to top. The dielectric aging phenomena occurs predominantly in ferroelectric ceramic materials and is more prominent with formulations exhibiting high dielectric constants, ie eia class 2 and 3. The development of microwave ceramics with high dielectric constant and good thermal stability together with small dielectric loss is a challenging problem in the area of dielectric resonator .
