1MHz/MHz Piezo Transducer Ceramic Disc for Flow Sensor

The commonly used electronic Piezoelectric ceramic are barium titanate system, lead zirconate titanate binary system. The third common compound of ABO3 type is added to the binary system.

If you continue to add the ternary to the system, a fourth or more compound. In this case, it is composed of Quaternary and multicomponent electronic ceramics. In addition, there is a metaniobate system, which is hard to find, such as "potassium sodium metaniobate" and barium strontium niobate (Bax · sr1-x · Nb2O5), etc. They do not contain toxic lead and other substandard components, which are beneficial to the environmental protection industry. Therefore, the dielectric properties formed by electronic ceramics, which are advocated, reflect the response of ceramic materials to the electromagnetic fields formed inside and outside. Generally speaking, when the constant ε 0 is used to compare the dielectric field, the response of the dielectric to the electric field can be linear when the external electromagnetic field is small.

Piezoelectric ceramic alumina ceramic is one of the most widely used ceramic materials in oxide ceramics.
