Commonly used electronic ceramics are barium titanate and lead zirconate titanate binary systems, to which a third common compound of ABO3 is added.

If you add a fourth or more compound to the system in the ternary. Such a case consists of a four-element, multi-element electronic ceramics. In addition, there is a metabniate system, difficult to find electronic ceramic types such as "sodium potassium metabniate" and barium strontium metabniate (Bax·Sr1-x·Nb2O5) and so on. They do not contain toxic lead and other unqualified components, which are beneficial to the environmental protection industry. Therefore, it is advocated that the dielectric property formed by electronic ceramics reflects the degree of response of the ceramic material to the electromagnetic field formed inside and outside. Generally speaking, the dielectric constant ε0 is compared to indicate that the dielectric response to the electric field has usable linearity when the external electromagnetic field is not large.
